Struct wasm_encoder::ExportSection

pub struct ExportSection { /* private fields */ }

An encoder for the export section.

Example

use wasm_encoder::{
    Export, ExportSection, TableSection, TableType, Module, ValType,
};

let mut tables = TableSection::new();
tables.table(TableType {
    element_type: ValType::FuncRef,
    minimum: 128,
    maximum: None,
});

let mut exports = ExportSection::new();
exports.export("my-table", Export::Table(0));

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

let wasm_bytes = module.finish();
