Definition and accessors of wasmtime_error_t.
Definition of wasmtime_extern_t and external items.
uint8_t * wasmtime_memory_data(const wasmtime_context_t *store, const wasmtime_memory_t *memory)
Returns the base pointer in memory where the linear memory starts.
uint64_t wasmtime_memorytype_minimum(const wasm_memorytype_t *ty)
Returns the minimum size, in pages, of the specified memory type.
wasmtime_error_t * wasmtime_memory_grow(wasmtime_context_t *store, const wasmtime_memory_t *memory, uint64_t delta, uint64_t *prev_size)
Attempts to grow the specified memory by delta pages.
wasm_memorytype_t * wasmtime_memorytype_new(uint64_t min, bool max_present, uint64_t max, bool is_64)
Creates a new memory type from the specified parameters.
bool wasmtime_memorytype_is64(const wasm_memorytype_t *ty)
Returns whether this type of memory represents a 64-bit memory.
bool wasmtime_memorytype_maximum(const wasm_memorytype_t *ty, uint64_t *max)
Returns the maximum size, in pages, of the specified memory type.
wasmtime_error_t * wasmtime_memory_new(wasmtime_context_t *store, const wasm_memorytype_t *ty, wasmtime_memory_t *ret)
Creates a new WebAssembly linear memory.
size_t wasmtime_memory_data_size(const wasmtime_context_t *store, const wasmtime_memory_t *memory)
Returns the byte length of this linear memory.
uint64_t wasmtime_memory_size(const wasmtime_context_t *store, const wasmtime_memory_t *memory)
Returns the length, in WebAssembly pages, of this linear memory.
wasm_memorytype_t * wasmtime_memory_type(const wasmtime_context_t *store, const wasmtime_memory_t *memory)
Returns the tyep of the memory specified.
An opaque object representing the type of a memory.
An interior pointer into a wasmtime_store_t which is used as "context" for many functions.
Errors generated by Wasmtime.
Representation of a memory in Wasmtime.
