Struct wasm_encoder::AliasSection

pub struct AliasSection { /* fields omitted */ }

An encoder for the alias section.

Note that this is part of the module linking proposal and is not currently part of stable WebAssembly.

Example

use wasm_encoder::{Module, AliasSection, ItemKind};

let mut aliases = AliasSection::new();
aliases.outer_type(0, 2);
aliases.instance_export(0, ItemKind::Function, "foo");

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

let wasm_bytes = module.finish();

Implementations

impl AliasSection

pub fn new() -> AliasSection
