Struct wasm_encoder::TypeSection

pub struct TypeSection { /* fields omitted */ }

An encoder for the type section.

Example

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

let mut types = TypeSection::new();
let params = vec![ValType::I32, ValType::I64];
let results = vec![ValType::I32];
types.function(params, results);

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

let wasm_bytes = module.finish();

Implementations

impl TypeSection

pub fn new() -> TypeSection

Create a new type section encoder.

pub fn len(&self) -> u32

How many types have been defined inside this section so far?

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.

pub fn module<'a, I, E>(&mut self, imports: I, exports: E) -> &mut Self where
    I: IntoIterator<Item = (&'a str, Option<&'a str>, EntityType)>,
    I::IntoIter: ExactSizeIterator,
    E: IntoIterator<Item = (&'a str, EntityType)>,
    E::IntoIter: ExactSizeIterator,
