Struct wasm_encoder::TagSection

pub struct TagSection { /* private fields */ }

An encoder for the tag section.

Example

use wasm_encoder::{Module, TagSection, TagType, TagKind};

let mut tags = TagSection::new();
tags.tag(TagType {
    kind: TagKind::Exception,
    func_type_idx: 0,
});

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

let wasm_bytes = module.finish();
