Implementations

impl Func

pub fn new<C: AsContextMut>( ctx: C, ty: FuncType, func: impl 'static + Send + Sync + Fn(StoreContextMut<'_, C::UserState, C::Engine>, &[Value], &mut [Value]) -> Result<()> ) -> Self

Creates a new Func with the given arguments.

pub fn ty<C: AsContext>(&self, ctx: C) -> FuncType

Returns the function type of the Func.

pub fn call<C: AsContextMut>( &self, ctx: C, args: &[Value], results: &mut [Value] ) -> Result<()>

Calls the Wasm or host function with the given inputs.

The result is written back into the outputs buffer.
