Struct wasm_encoder::ProducersSection

pub struct ProducersSection { /* private fields */ }

An encoder for the producers custom section.

This section is a non-standard convention that is supported by many toolchains.

Example

use wasm_encoder::{ProducersSection, ProducersField, Module};

// Create a new producers section.
let mut field = ProducersField::new();
field.value("clang", "14.0.4");
field.value("rustc", "1.66.1 (90743e729 2023-01-10)");
let mut producers = ProducersSection::new();
producers.field("processed-by", &field);

// Add the producers section to a new Wasm module and get the encoded bytes.
let mut module = Module::new();
module.section(&producers);
let wasm_bytes = module.finish();

Implementations

impl ProducersSection

pub fn new() -> Self

Construct an empty encoder for the producers custom section.

pub fn field(&mut self, name: &str, values: &ProducersField) -> &mut Self

Add a field to the section. The spec recommends names for this section are “language”, “processed-by”, and “sdk”. Each field in section must have a unique name.
