Struct ComponentAliasSection

pub struct ComponentAliasSection { /* private fields */ }

Available on crate feature component-model only.

An encoder for the alias section of WebAssembly component.

Example

use wasm_encoder::{Component, Alias, ComponentAliasSection, ComponentExportKind, ComponentOuterAliasKind};

let mut aliases = ComponentAliasSection::new();
aliases.alias(Alias::InstanceExport { instance: 0, kind: ComponentExportKind::Func, name: "f" });
aliases.alias(Alias::Outer { count: 0, kind: ComponentOuterAliasKind::Type, index: 1 });

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

let bytes = component.finish();
