Struct wasm_encoder::ComponentStartSection

pub struct ComponentStartSection<A> {
    pub function_index: u32,
    pub args: A,
    pub results: u32,
}

An encoder for the start section of WebAssembly components.

Example

use wasm_encoder::{Component, ComponentStartSection};

let start = ComponentStartSection { function_index: 0, args: [0, 1], results: 1 };

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

let bytes = component.finish();

Fields

function_index: u32

The index to the start function.

args: A

The arguments to pass to the start function.

An argument is an index to a value.

results: u32

The number of expected results for the start function.

This should match the number of results for the type of the function referenced by function_index.
