Struct wasm_encoder::ComponentAliasSection

pub struct ComponentAliasSection { /* private fields */ }

An encoder for the alias section of WebAssembly component.

Example

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

let mut aliases = ComponentAliasSection::new();
aliases.instance_export(0, ComponentExportKind::Func, "f");
aliases.outer(0, ComponentOuterAliasKind::Type, 1);

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

let bytes = component.finish();

Implementations

impl ComponentAliasSection

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_index: u32,
    kind: ComponentExportKind,
    name: &str
) -> &mut Self

Define an alias to a component instance’s export.

pub fn core_instance_export(
    &mut self,
    instance_index: u32,
    kind: ExportKind,
    name: &str
) -> &mut Self

Define an alias to a core instance’s export.

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

Define an alias to an outer component item.

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