Struct wasm_encoder::AliasSection

pub struct AliasSection { /* private fields */ }

An encoder for the core alias section of WebAssembly components.

Example

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

let mut aliases = AliasSection::new();
aliases.instance_export(0, ExportKind::Func, "f");

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

let bytes = component.finish();

Implementations

impl AliasSection

pub fn new() -> Self

Create a new core 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_index: u32,
    kind: ExportKind,
    name: &str
) -> &mut Self

Define an alias to an instance’s export.

pub fn outer(
    &mut self,
    count: u32,
    kind: CoreOuterAliasKind,
    index: u32
) -> &mut Self

Define an alias to an outer core item.

The count starts at 0 to indicate the current component, 1 indicates the direct parent, 2 the grandparent, etc.
