Struct wasm_encoder::InstanceSection

pub struct InstanceSection { /* fields omitted */ }

An encoder for the instance section.

Note that this is part of the module linking proposal and is not currently part of stable WebAssembly.

Example

use wasm_encoder::{Module, InstanceSection, Export};

let mut instances = InstanceSection::new();
instances.instantiate(0, vec![
    Export::Function(0),
    Export::Module(2),
    Export::Global(0),
]);

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

let wasm_bytes = module.finish();

Implementations

impl InstanceSection

pub fn new() -> InstanceSection

Construct a new instance section encoder.

pub fn instantiate<I>(&mut self, module: u32, args: I) -> &mut Self where
    I: IntoIterator<Item = Export>,
    I::IntoIter: ExactSizeIterator, 

Define an instantiation of the given module with the given items as arguments to the instantiation.

Trait Implementations

pub fn id(&self) -> u8

pub fn encode<S>(&self, sink: &mut S) where
    S: Extend<u8>,
