Struct wasmtime::TypedFunc

#[repr(transparent)]
pub struct TypedFunc<Params, Results> { /* fields omitted */ }

A statically typed WebAssembly function.

Values of this type represent statically type-checked WebAssembly functions. The function within a TypedFunc is statically known to have Params as its parameters and Results as its results.

This structure is created via Func::typed or Func::typed_unchecked. For more documentation about this see those methods.

Implementations

impl<Params, Results> TypedFunc<Params, Results> where
    Params: WasmParams,
    Results: WasmResults, 

pub fn func(&self) -> &Func

Returns the underlying Func that this is wrapping, losing the static type information in the process.

pub fn call(&self, params: Params) -> Result<Results, Trap>

Invokes this WebAssembly function with the specified parameters.

Returns either the results of the call, or a Trap if one happened.

For more information, see the Func::typed and Func::call documentation.

Panics

This function will panic if it is called when the underlying Func is connected to an asynchronous store.

pub async fn call_async(&self, params: Params) -> Result<Results, Trap>

Invokes this WebAssembly function with the specified parameters.

Returns either the results of the call, or a Trap if one happened.

For more information, see the Func::typed and Func::call_async documentation.

Panics

This function will panic if it is called when the underlying Func is connected to a synchronous store.

Trait Implementations

impl<Params, Results> Clone for TypedFunc<Params, Results>

fn clone(&self) -> TypedFunc<Params, Results>

Returns a copy of the value.

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

Performs copy-assignment from source.
