Struct wasm_encoder::ComponentInstanceSection

source ·
pub struct ComponentInstanceSection { /* private fields */ }
Expand description

An encoder for the instance section of WebAssembly components.

§Example

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

let mut instances = ComponentInstanceSection::new();
instances.export_items([("foo", ComponentExportKind::Func, 0)]);
instances.instantiate(1, [("foo", ComponentExportKind::Instance, 0)]);

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

let bytes = component.finish();
