Struct wasm_encoder::AliasSection

pub struct AliasSection { /* private fields */ }

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() -> Self

Construct a new alias section encoder.

pub fn len(&self) -> u32

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

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn instance_export(
    &mut self,
    instance: u32,
    kind: ItemKind,
    name: &str
) -> &mut Self

Define an alias that references the export of a defined instance.

pub fn outer_type(&mut self, depth: u32, ty: u32) -> &mut Self

pub fn outer_module(&mut self, depth: u32, module: u32) -> &mut Self
