Detailed Description

Representation of a WebAssembly anyref value.

Member Function Documentation

i31()

static AnyRef wasmtime::AnyRef::i31 ( Store::Context  cx, uint32_t  value  )

inlinestatic

Creates a new AnyRef which is an i31 with the given value, truncated if the upper bit is set.

raw()

const wasmtime_anyref_t * wasmtime::AnyRef::raw ( ) const

inline

Returns the raw underlying C API value.

This class still retains ownership of the pointer.

unroot()

void wasmtime::AnyRef::unroot ( Store::Context  cx )

inline

Unroots this value from the context provided, enabling a future GC to collect the internal object if there are no more references.
