Struct CoreTypeSection

pub struct CoreTypeSection { /* private fields */ }

Available on crate feature component-model only.

An encoder for the core type section of WebAssembly components.

Example

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

let mut types = CoreTypeSection::new();

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

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

let bytes = component.finish();

Implementations

impl CoreTypeSection

pub fn new() -> Self

Create a new core type section encoder.

pub fn len(&self) -> u32

The number of types in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

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

Encode a type into this section.

The returned encoder must be finished before adding another type.
