Implementations

impl Function

pub(crate) fn new_with_env<FT, F, T: Send + 'static>( store: &mut impl AsStoreMut, env: &FunctionEnv<T>, ty: FT, func: F, ) -> Self

where FT: Into<FunctionType>, F: Fn(FunctionEnvMut<'_, T>, &[Value]) -> Result<Vec<Value>, RuntimeError> + 'static + Send + Sync,

pub(crate) fn new_typed<F, Args, Rets>( store: &mut impl AsStoreMut, func: F, ) -> Self

where F: HostFunction<(), Args, Rets, WithoutEnv> + 'static + Send + Sync, Args: WasmTypeList, Rets: WasmTypeList,

Creates a new host Function from a native function.

pub(crate) fn new_typed_with_env<T: Send + 'static, F, Args, Rets>( store: &mut impl AsStoreMut, env: &FunctionEnv<T>, func: F, ) -> Self

where F: HostFunction<T, Args, Rets, WithEnv> + 'static + Send + Sync, Args: WasmTypeList, Rets: WasmTypeList,

pub(crate) fn ty(&self, store: &impl AsStoreRef) -> FunctionType

fn call_wasm( &self, store: &mut impl AsStoreMut, trampoline: VMTrampoline, params: &[Value], results: &mut [Value], ) -> Result<(), RuntimeError>

fn call_wasm_raw( &self, store: &mut impl AsStoreMut, trampoline: VMTrampoline, params: Vec<RawValue>, results: &mut [Value], ) -> Result<(), RuntimeError>

pub(crate) fn result_arity(&self, store: &impl AsStoreRef) -> usize

pub(crate) fn call( &self, store: &mut impl AsStoreMut, params: &[Value], ) -> Result<Box<[Value]>, RuntimeError>

pub(crate) fn vm_funcref(&self, store: &impl AsStoreRef) -> VMFuncRef

pub(crate) unsafe fn from_vm_funcref( store: &mut impl AsStoreMut, funcref: VMFuncRef, ) -> Self

pub(crate) fn from_vm_extern( store: &mut impl AsStoreMut, vm_extern: VMExternFunction, ) -> Self

pub(crate) fn is_from_store(&self, store: &impl AsStoreRef) -> bool

Checks whether this Function can be used with the given store.

pub(crate) fn to_vm_extern(&self) -> VMExtern

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl From<StoreHandle<VMFunction>> for Function

fn from(handle: StoreHandle<VMFunction>) -> Self

Converts to this type from the input type.

impl PartialEq for Function

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

Tests for self and other values to be equal, and is used by ==.

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

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