Struct ComponentFuncTypeEncoder 

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

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>,

Available on crate feature component-model only.

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: Option<ComponentValType>) -> &mut Self

Available on crate feature component-model only.

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.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
