Struct wasm_encoder::TypeSection

pub struct TypeSection { /* private fields */ }

An encoder for the type section of WebAssembly modules.

Example

use wasm_encoder::{Module, TypeSection, ValType};

let mut types = TypeSection::new();

types.function([ValType::I32, ValType::I32], [ValType::I64]);

let mut module = Module::new();
module.section(&types);

let bytes = module.finish();

Implementations

impl TypeSection

pub fn new() -> Self

Create a new module 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 function<P, R>(&mut self, params: P, results: R) -> &mut Self where
    P: IntoIterator<Item = ValType>,
    P::IntoIter: ExactSizeIterator,
    R: IntoIterator<Item = ValType>,
    R::IntoIter: ExactSizeIterator, 

Define a function type in this type section.
