Struct ComponentExportSection

pub struct ComponentExportSection { /* private fields */ }

Available on crate feature component-model only.

An encoder for the export section of WebAssembly component.

Example

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

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

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

let bytes = component.finish();

Implementations

impl ComponentExportSection

pub fn new() -> Self

pub fn is_empty(&self) -> bool

Determines if the section is empty.

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

Define an export in the export section.
