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.

take_raw()

uint32_t wasmtime::AnyRef::take_raw ( Store::Context  cx )

inline

Consumes ownership of the underlying wasmtime_anyref_t and returns the result of wasmtime_anyref_to_raw.
