Struct wasm_encoder::FunctionSection

pub struct FunctionSection { /* private fields */ }

An encoder for the function section of WebAssembly modules.

Example

use wasm_encoder::{Module, FunctionSection, ValType};

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

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

// Note: this will generate an invalid module because we didn't generate a
// code section containing the function body. See the documentation for
// `CodeSection` for details.

let bytes = module.finish();

Implementations

impl FunctionSection

pub fn new() -> Self
