Struct wasm_component_layer::TypedFunc

pub struct TypedFunc<P: ComponentList, R: ComponentList> { /* private fields */ }

A strongly-typed component model function that can be called to interact with Instances.

Implementations

impl<P: ComponentList, R: ComponentList> TypedFunc<P, R>

pub fn new<C: AsContextMut>( ctx: C, f: impl 'static + Send + Sync + Fn(StoreContextMut<'_, C::UserState, C::Engine>, P) -> Result<R> ) -> Self

Creates a new function, wrapping the given closure.

pub fn call(&self, ctx: impl AsContextMut, params: P) -> Result<R>

Calls this function, returning an error if:

• The store did not match the original.
• A trap occurred.

pub fn func(&self) -> Func

Gets the underlying, untyped function.

pub fn ty(&self) -> FuncType

Gets the component model type of this function.
