Typedef Documentation

◆ wasmtime_func_t

Representation of a function in Wasmtime.

Functions are represented with a 64-bit identifying integer in Wasmtime. They do not have any destructor associated with them. Functions cannot interoperate between wasmtime_store_t instances and if the wrong function is passed to the wrong store then it may trigger an assertion to abort the process.

◆ wasmtime_global_t

Representation of a global in Wasmtime.

Globals are represented with a 64-bit identifying integer in Wasmtime. They do not have any destructor associated with them. Globals cannot interoperate between wasmtime_store_t instances and if the wrong global is passed to the wrong store then it may trigger an assertion to abort the process.

◆ wasmtime_memory_t

Representation of a memory in Wasmtime.

Memories are represented with a 64-bit identifying integer in Wasmtime. They do not have any destructor associated with them. Memories cannot interoperate between wasmtime_store_t instances and if the wrong memory is passed to the wrong store then it may trigger an assertion to abort the process.

◆ wasmtime_table_t

Representation of a table in Wasmtime.

Tables are represented with a 64-bit identifying integer in Wasmtime. They do not have any destructor associated with them. Tables cannot interoperate between wasmtime_store_t instances and if the wrong table is passed to the wrong store then it may trigger an assertion to abort the process.

Function Documentation

◆ wasmtime_extern_type()

wasm_externtype_t * wasmtime_extern_type ( wasmtime_context_t context,
wasmtime_extern_t val 
)

Returns the type of the wasmtime_extern_t defined within the given store.

Does not take ownership of context or val, but the returned wasm_externtype_t is an owned value that needs to be deleted.
