Struct wasm_encoder::Module

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

Represents a WebAssembly component that is being encoded.

Sections within a WebAssembly module are encoded in a specific order.

Modules may also added as a section to a WebAssembly component.

Implementations§

source§

impl Module

source

pub const HEADER: [u8; 8] = _

The 8-byte header at the beginning of all core wasm modules.

source

pub fn new() -> Self

Begin writing a new Module.

source

pub fn section(&mut self, section: &impl Section) -> &mut Self

Write a section into this module.

It is your responsibility to define the sections in the proper order, and to ensure that each kind of section (other than custom sections) is only defined once. While this is a potential footgun, it also allows you to use this crate to easily construct test cases for bad Wasm module encodings.

source

pub fn as_slice(&self) -> &[u8]

Get the encoded Wasm module as a slice.

source

pub fn len(&self) -> usize

Give the current size of the module in bytes.

source

pub fn finish(self) -> Vec<u8>

Finish writing this Wasm module and extract ownership of the encoded bytes.
