Types that qualify as Wasm function types for validation purposes.

Required Methods

fn len_inputs(&self) -> usize

Returns the number of input types.

fn len_outputs(&self) -> usize

Returns the number of output types.

fn input_at(&self, at: u32) -> Option<ValType>

Returns the type at given index if any.

Note

The returned type may be wrapped by the user crate and thus the actually returned type only has to be comparable to a Wasm type.

fn output_at(&self, at: u32) -> Option<ValType>

Returns the type at given index if any.

Note

The returned type may be wrapped by the user crate and thus the actually returned type only has to be comparable to a Wasm type.

Provided Methods

fn inputs(&self) -> WasmFuncTypeInputs<'_, Self> where Self: Sized,

Returns the list of inputs as an iterator.

fn outputs(&self) -> WasmFuncTypeOutputs<'_, Self> where Self: Sized,

Returns the list of outputs as an iterator.
