pub struct CoreTypeSection { /* private fields */ }
Expand description

An encoder for the core type section of WebAssembly components.

Example

use wasm_encoder::{Component, CoreTypeSection, ModuleType};

let mut types = CoreTypeSection::new();

types.module(&ModuleType::new());

let mut component = Component::new();
component.section(&types);

let bytes = component.finish();

Implementations§

source§

impl CoreTypeSection

source

pub fn new() -> Self

Create a new core type section encoder.

source

pub fn len(&self) -> u32

The number of types in the section.

source

pub fn is_empty(&self) -> bool

Determines if the section is empty.

source

pub fn ty(&mut self) -> CoreTypeEncoder<'_>

Encode a type into this section.

The returned encoder must be finished before adding another type.

source

pub fn function<P, R>(&mut self, params: P, results: R) -> &mut Selfwhere P: IntoIterator<Item = ValType>, P::IntoIter: ExactSizeIterator, R: IntoIterator<Item = ValType>, R::IntoIter: ExactSizeIterator,

Define a function type in this type section.

source

pub fn module(&mut self, ty: &ModuleType) -> &mut Self

Define a module type in this type section.

Currently this is only used for core type sections in components.
