Detailed Description

Wasmtime-specific extensions for wasm_valtype_t and structures for working with the full breadth of value types in the wasm type system.

Typedef Documentation

wasmtime_valtype_t

typedef struct wasmtime_valtype wasmtime_valtype_t

A WebAssembly value type.

Note that this is a parallel representation to wasm_valtype_t which is intended to support the entire breadth of WebAssembly that wasmtime supports.

Function Documentation

wasmtime_heaptype_delete()

WASM_API_EXTERN void wasmtime_heaptype_delete

(

wasmtime_heaptype_t *

ty

)

Deletes any payload of ty, if applicable.

Only necessary to call for concrete types.

wasmtime_reftype_delete()

WASM_API_EXTERN void wasmtime_reftype_delete

(

wasmtime_reftype_t *

ty

)

Deletes any payload of ty, if applicable.

Only necessary if ty->heaptype is concrete.

wasmtime_valtype_delete()

WASM_API_EXTERN void wasmtime_valtype_delete

(

wasmtime_valtype_t *

ty

)

Deletes any payload of ty, if applicable.

Only necessary when ty is a concrete reference type.

wasmtime_valtype_to_wasm()

WASM_API_EXTERN wasm_valtype_t * wasmtime_valtype_to_wasm	(	const wasm_engine_t *	engine,
		const wasmtime_valtype_t *	ty
	)

Converts ty into a wasm_valtype_t and returns a pointer to it.

The caller must deallocate the returned value.
