Struct ComponentFuncTypeEncoder

pub struct ComponentFuncTypeEncoder<'a> { /* private fields */ }

Available on crate feature component-model only.

Used to encode component function types.

Implementations

impl<'a> ComponentFuncTypeEncoder<'a>

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.

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.

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.
