Struct wasmtime_environ::WasmFuncType

pub struct WasmFuncType { /* private fields */ }

WebAssembly function type – equivalent of wasmparser’s FuncType.

Implementations

impl WasmFuncType

pub fn new( params: Box<[WasmValType]>, returns: Box<[WasmValType]> ) -> WasmFuncType

pub fn params(&self) -> &[WasmValType]

Function params types.

pub fn non_i31_gc_ref_params_count(&self) -> usize

How many externrefs are in this function’s params?

pub fn returns(&self) -> &[WasmValType]

Returns params types.

pub fn non_i31_gc_ref_returns_count(&self) -> usize

How many externrefs are in this function’s returns?

Trait Implementations

impl Clone for WasmFuncType

fn clone(&self) -> WasmFuncType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasmFuncType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WasmFuncType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for WasmFuncType

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 WasmFuncType

fn eq(&self, other: &WasmFuncType) -> 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 WasmFuncType

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 WasmFuncType

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.
