Struct wasm_encoder::CodeSection

pub struct CodeSection { /* fields omitted */ }

An encoder for the code section.

Example

use wasm_encoder::{
    CodeSection, Function, FunctionSection, Instruction, Module,
    TypeSection, ValType
};

let mut types = TypeSection::new();
types.function(vec![], vec![ValType::I32]);

let mut functions = FunctionSection::new();
let type_index = 0;
functions.function(type_index);

let locals = vec![];
let mut func = Function::new(locals);
func.instruction(Instruction::I32Const(42));
let mut code = CodeSection::new();
code.function(&func);

let mut module = Module::new();
module
    .section(&types)
    .section(&functions)
    .section(&code);

let wasm_bytes = module.finish();
