Specifier of what optimization level to use for generated JIT code.

See wasmtime_opt_level_enum for possible values.

◆ wasmtime_profiling_strategy_t

typedef uint8_t wasmtime_profiling_strategy_t

Different ways wasmtime can enable profiling JIT code.

See wasmtime_profiling_strategy_enum for possible values.

Enumeration Type Documentation

◆ wasmtime_opt_level_enum

enum wasmtime_opt_level_enum

Different ways Wasmtime can optimize generated code.

The default value is WASMTIME_OPT_LEVEL_SPEED.

Enumerator
WASMTIME_OPT_LEVEL_NONE	Generated code will not be optimized at all.
WASMTIME_OPT_LEVEL_SPEED	Generated code will be optimized purely for speed.
WASMTIME_OPT_LEVEL_SPEED_AND_SIZE	Generated code will be optimized, but some speed optimizations are disabled if they cause the generated code to be significantly larger.

◆ wasmtime_profiling_strategy_enum

enum wasmtime_profiling_strategy_enum

Different ways to profile JIT code.

The default is WASMTIME_PROFILING_STRATEGY_NONE.

Enumerator
WASMTIME_PROFILING_STRATEGY_NONE	No profiling is enabled at runtime.
WASMTIME_PROFILING_STRATEGY_JITDUMP	Linux's "jitdump" support in `perf` is enabled and when Wasmtime is run under `perf` necessary calls will be made to profile generated JIT code.
WASMTIME_PROFILING_STRATEGY_VTUNE	Support for VTune will be enabled and the VTune runtime will be informed, at runtime, about JIT code. Note that this isn't always enabled at build time.
WASMTIME_PROFILING_STRATEGY_PERFMAP	Linux's simple "perfmap" support in `perf` is enabled and when Wasmtime is run under `perf` necessary calls will be made to profile generated JIT code.

◆ wasmtime_strategy_enum

enum wasmtime_strategy_enum

Different ways that Wasmtime can compile WebAssembly.

The default value is WASMTIME_STRATEGY_AUTO.

Enumerator
WASMTIME_STRATEGY_AUTO	Automatically picks the compilation backend, currently always defaulting to Cranelift.
WASMTIME_STRATEGY_CRANELIFT	Indicates that Wasmtime will unconditionally use Cranelift to compile WebAssembly code.

Function Documentation

◆ wasmtime_config_cache_config_load()

wasmtime_error_t * wasmtime_config_cache_config_load	(	wasm_config_t *	,
		const char *
	)

Enables Wasmtime's cache and loads configuration from the specified path.

By default the Wasmtime compilation cache is disabled. The configuration path here can be NULL to use the default settings, and otherwise the argument here must be a file on the filesystem with TOML configuration - https://bytecodealliance.github.io/wasmtime/cli-cache.html.

An error is returned if the cache configuration could not be loaded or if the cache could not be enabled.

◆ wasmtime_config_consume_fuel_set()

void wasmtime_config_consume_fuel_set	(	wasm_config_t *	,
		bool
	)

Whether or not fuel is enabled for generated code.

This setting is false by default. When enabled it will enable fuel counting meaning that fuel will be consumed every time a wasm instruction is executed, and trap when reaching zero.

◆ wasmtime_config_cranelift_debug_verifier_set()

void wasmtime_config_cranelift_debug_verifier_set	(	wasm_config_t *	,
		bool
	)

Configures whether Cranelift's debug verifier is enabled.

This setting in false by default.

When cranelift is used for compilation this enables expensive debug checks within Cranelift itself to verify it's correct.

◆ wasmtime_config_cranelift_flag_enable()

void wasmtime_config_cranelift_flag_enable	(	wasm_config_t *	,
		const char *
	)

Enables a target-specific flag in Cranelift.

This can be used, for example, to enable SSE4.2 on x86_64 hosts. Settings can be explored with wasmtime settings on the CLI.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.cranelift_flag_enable

◆ wasmtime_config_cranelift_flag_set()

void wasmtime_config_cranelift_flag_set	(	wasm_config_t *	,
		const char *	key,
		const char *	value
	)

Sets a target-specific flag in Cranelift to the specified value.

This can be used, for example, to enable SSE4.2 on x86_64 hosts. Settings can be explored with wasmtime settings on the CLI.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.cranelift_flag_set

◆ wasmtime_config_cranelift_nan_canonicalization_set()

void wasmtime_config_cranelift_nan_canonicalization_set	(	wasm_config_t *	,
		bool
	)

Configures whether Cranelift should perform a NaN-canonicalization pass.

When Cranelift is used as a code generation backend this will configure it to replace NaNs with a single canonical value. This is useful for users requiring entirely deterministic WebAssembly computation.

This is not required by the WebAssembly spec, so it is not enabled by default.

The default value for this is false

◆ wasmtime_config_cranelift_opt_level_set()

void wasmtime_config_cranelift_opt_level_set	(	wasm_config_t *	,
		wasmtime_opt_level_t
	)

Configures Cranelift's optimization level for JIT code.

This setting in WASMTIME_OPT_LEVEL_SPEED by default.

◆ wasmtime_config_debug_info_set()

void wasmtime_config_debug_info_set	(	wasm_config_t *	,
		bool
	)

Configures whether DWARF debug information is constructed at runtime to describe JIT code.

This setting is false by default. When enabled it will attempt to inform native debuggers about DWARF debugging information for JIT code to more easily debug compiled WebAssembly via native debuggers. This can also sometimes improve the quality of output when profiling is enabled.

◆ wasmtime_config_dynamic_memory_guard_size_set()

void wasmtime_config_dynamic_memory_guard_size_set	(	wasm_config_t *	,
		uint64_t
	)

Configures the guard region size for "dynamic" memory.

For more information see the Rust documentation at https://bytecodealliance.github.io/wasmtime/api/wasmtime/struct.Config.html#method.dynamic_memory_guard_size.

◆ wasmtime_config_dynamic_memory_reserved_for_growth_set()

void wasmtime_config_dynamic_memory_reserved_for_growth_set	(	wasm_config_t *	,
		uint64_t
	)

Configures the size, in bytes, of the extra virtual memory space reserved after a “dynamic” memory for growing into.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.dynamic_memory_reserved_for_growth

◆ wasmtime_config_epoch_interruption_set()

void wasmtime_config_epoch_interruption_set	(	wasm_config_t *	,
		bool
	)

Whether or not epoch-based interruption is enabled for generated code.

This setting is false by default. When enabled wasm code will check the current epoch periodically and abort if the current epoch is beyond a store-configured limit.

Note that when this setting is enabled all stores will immediately trap and need to have their epoch deadline otherwise configured with wasmtime_context_set_epoch_deadline.

Note that the current epoch is engine-local and can be incremented with wasmtime_engine_increment_epoch.

◆ wasmtime_config_host_memory_creator_set()

void wasmtime_config_host_memory_creator_set	(	wasm_config_t *	,
		wasmtime_memory_creator_t *
	)

Sets a custom memory creator.

Custom memory creators are used when creating host Memory objects or when creating instance linear memories for the on-demand instance allocation strategy.

The config does not take ownership of the wasmtime_memory_creator_t passed in, but instead copies all the values in the struct.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.with_host_memory

◆ wasmtime_config_macos_use_mach_ports_set()

void wasmtime_config_macos_use_mach_ports_set	(	wasm_config_t *	,
		bool
	)

Configures whether, when on macOS, Mach ports are used for exception handling instead of traditional Unix-based signal handling.

This option defaults to true, using Mach ports by default.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.macos_use_mach_ports

◆ wasmtime_config_max_wasm_stack_set()

void wasmtime_config_max_wasm_stack_set	(	wasm_config_t *	,
		size_t
	)

Configures the maximum stack size, in bytes, that JIT code can use.

This setting is 2MB by default. Configuring this setting will limit the amount of native stack space that JIT code can use while it is executing. If you're hitting stack overflow you can try making this setting larger, or if you'd like to limit wasm programs to less stack you can also configure this.

Note that this setting is not interpreted with 100% precision. Additionally the amount of stack space that wasm takes is always relative to the first invocation of wasm on the stack, so recursive calls with host frames in the middle will all need to fit within this setting.

◆ wasmtime_config_memory_init_cow_set()

void wasmtime_config_memory_init_cow_set	(	wasm_config_t *	,
		bool
	)

Configures whether copy-on-write memory-mapped data is used to initialize a linear memory.

Initializing linear memory via a copy-on-write mapping can drastically improve instantiation costs of a WebAssembly module because copying memory is deferred. Additionally if a page of memory is only ever read from WebAssembly and never written too then the same underlying page of data will be reused between all instantiations of a module meaning that if a module is instantiated many times this can lower the overall memory required needed to run that module.

This option defaults to true.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.memory_init_cow

◆ wasmtime_config_native_unwind_info_set()

void wasmtime_config_native_unwind_info_set	(	wasm_config_t *	,
		bool
	)

Configures whether to generate native unwind information (e.g. .eh_frame on Linux).

This option defaults to true.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.native_unwind_info

◆ wasmtime_config_parallel_compilation_set()

void wasmtime_config_parallel_compilation_set	(	wasm_config_t *	,
		bool
	)

Configure whether wasmtime should compile a module using multiple threads.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.parallel_compilation.

◆ wasmtime_config_profiler_set()

void wasmtime_config_profiler_set	(	wasm_config_t *	,
		wasmtime_profiling_strategy_t
	)

Configures the profiling strategy used for JIT code.

This setting in WASMTIME_PROFILING_STRATEGY_NONE by default.

◆ wasmtime_config_static_memory_forced_set()

void wasmtime_config_static_memory_forced_set	(	wasm_config_t *	,
		bool
	)

Configures the “static” style of memory to always be used.

This setting is false by default.

For more information see the Rust documentation at https://bytecodealliance.github.io/wasmtime/api/wasmtime/struct.Config.html#method.static_memory_forced.

void wasmtime_config_static_memory_guard_size_set	(	wasm_config_t *	,
		uint64_t
	)

Configures the guard region size for "static" memory.

For more information see the Rust documentation at https://bytecodealliance.github.io/wasmtime/api/wasmtime/struct.Config.html#method.static_memory_guard_size.

		uint64_t
	)

Configures the maximum size for memory to be considered "static".

For more information see the Rust documentation at https://bytecodealliance.github.io/wasmtime/api/wasmtime/struct.Config.html#method.static_memory_maximum_size.

◆ wasmtime_config_strategy_set()

void wasmtime_config_strategy_set	(	wasm_config_t *	,
		wasmtime_strategy_t
	)

Configures how JIT code will be compiled.

This setting is WASMTIME_STRATEGY_AUTO by default.

◆ wasmtime_config_target_set()

wasmtime_error_t * wasmtime_config_target_set	(	wasm_config_t *	,
		const char *
	)

Configures the target triple that this configuration will produce machine code for.

This option defaults to the native host. Calling this method will additionally disable inference of the native features of the host (e.g. detection of SSE4.2 on x86_64 hosts). Native features can be reenabled with the cranelift_flag_{set,enable} properties.

For more information see the Rust documentation at https://docs.wasmtime.dev/api/wasmtime/struct.Config.html#method.config
