Struct wasm_encoder::ComponentFuncTypeEncoder

source ·
pub struct ComponentFuncTypeEncoder<'a> { /* private fields */ }
Expand description

Used to encode component function types.

Implementations§

source§

impl<'a> ComponentFuncTypeEncoder<'a>

source

pub fn params<'b, P, T>(&mut self, params: P) -> &mut Self
where P: IntoIterator<Item = (&'b str, T)>, P::IntoIter: ExactSizeIterator, T: Into<ComponentValType>,

Defines named parameters.

Parameters must be defined before defining results.

§Panics

This method will panic if the function is called twice since parameters can only be encoded once.

source

pub fn result(&mut self, ty: impl Into<ComponentValType>) -> &mut Self

Defines a single unnamed result.

This method cannot be used with results.

§Panics

This method will panic if the function is called twice, called before the params method, or called in addition to the results method.

source

pub fn results<'b, R, T>(&mut self, results: R) -> &mut Self
where R: IntoIterator<Item = (&'b str, T)>, R::IntoIter: ExactSizeIterator, T: Into<ComponentValType>,

Defines named results.

This method cannot be used with result.

§Panics

This method will panic if the function is called twice, called before the params method, or called in addition to the result method.
