Detailed Description

Representation of a WebAssembly eqref value.

An eqref is a reference to a GC object that supports equality testing. Subtypes include structref, arrayref, and i31ref.

Like all GC references, EqRef values are rooted in a Store and must be unrooted (by destruction or move) to allow garbage collection.

std::optional< int32_t > wasmtime::EqRef::i31_get_s ( Store::Context cx ) const

inline

Get the i31 value as a signed 32-bit integer. Returns std::nullopt if this eqref is not an i31ref.

std::optional< uint32_t > wasmtime::EqRef::i31_get_u ( Store::Context cx ) const

inline

Get the i31 value as an unsigned 32-bit integer. Returns std::nullopt if this eqref is not an i31ref.
