Struct wasm_encoder::ComponentExportSection

pub struct ComponentExportSection { /* private fields */ }

An encoder for the export section of WebAssembly component.

Example

use wasm_encoder::{Component, ComponentExportSection, ComponentExportKind, ComponentExternName};

// This exports a function named "foo"
let mut exports = ComponentExportSection::new();
let name = ComponentExternName::Kebab("foo");
exports.export(name, ComponentExportKind::Func, 0, None);

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

let bytes = component.finish();

Implementations

impl ComponentExportSection

pub fn new() -> Self

Create a new component export section encoder.

pub fn len(&self) -> u32

The number of exports in the section.

pub fn is_empty(&self) -> bool

Determines if the section is empty.

pub fn export( &mut self, name: impl AsComponentExternName, kind: ComponentExportKind, index: u32, ty: Option<ComponentTypeRef> ) -> &mut Self

Define an export in the export section.
