Struct wasmtime_environ::WasmRefType

pub struct WasmRefType {
    pub nullable: bool,
    pub heap_type: WasmHeapType,
}

WebAssembly reference type – equivalent of wasmparser’s RefType

Fields

nullable: bool

heap_type: WasmHeapType

Implementations

impl WasmRefType

pub const EXTERNREF: WasmRefType = _

pub const FUNCREF: WasmRefType = _

pub fn is_gc_heap_type(&self) -> bool

Is this a GC type that is allocated within the GC heap? (As opposed to i31ref which is a GC type that is not allocated on the GC heap.)

Trait Implementations

impl Clone for WasmRefType

fn clone(&self) -> WasmRefType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WasmRefType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WasmRefType

fn deserialize<__D>( __deserializer: __D ) -> Result<WasmRefType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for WasmRefType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for WasmRefType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WasmRefType

fn eq(&self, other: &WasmRefType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for WasmRefType

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeTrace for WasmRefType

fn trace<F, E>(&self, func: &mut F) -> Result<(), E>

where F: FnMut(EngineOrModuleTypeIndex) -> Result<(), E>,

Visit each edge.

fn trace_mut<F, E>(&mut self, func: &mut F) -> Result<(), E>

where F: FnMut(&mut EngineOrModuleTypeIndex) -> Result<(), E>,

Visit each edge, mutably.

fn canonicalize<F>(&mut self, module_to_engine: &mut F)

where F: FnMut(ModuleInternedTypeIndex) -> u32,

Canonicalize self by rewriting all type references inside self from module-level interned type indices to engine-level interned type indices.
