Struct wasm_encoder::GlobalSection

pub struct GlobalSection { /* fields omitted */ }

An encoder for the global section.

Example

use wasm_encoder::{Module, GlobalSection, GlobalType, Instruction, ValType};

let mut globals = GlobalSection::new();
globals.global(
    GlobalType {
        val_type: ValType::I32,
        mutable: false,
    },
    Instruction::I32Const(42),
);

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

let wasm_bytes = module.finish();
