Struct wasm_encoder::AliasSection

pub struct AliasSection { /* private fields */ }

An encoder for the alias section of WebAssembly component.

Example

use wasm_encoder::{Component, AliasSection, AliasExportKind};

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

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

let bytes = component.finish();

Implementations

impl AliasSection

pub fn new() -> Self

Create a new alias section encoder.

pub fn len(&self) -> u32

The number of aliases in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

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

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

pub fn outer_type(&mut self, count: u32, index: u32) -> &mut Self

Define an alias to an outer type.

The count starts at 0 to represent the current component.

pub fn outer_module(&mut self, count: u32, index: u32) -> &mut Self

Define an alias to an outer module.

The count starts at 0 to represent the current component.

pub fn outer_component(&mut self, count: u32, index: u32) -> &mut Self

Define an alias to an outer component.

The count starts at 0 to represent the current component.
