# ``WasmParser``
A WebAssembly binary parser library.
## Overview
WasmParser is a library for parsing WebAssembly binary format. It provides a parser for [WebAssembly binary format](https://webassembly.github.io/spec/core/binary/index.html).
## Quick start
To parse a WebAssembly binary file, you can use the `Parser` struct and its `parseNext()` method to incrementally parse the binary.
```swift
import WasmParser
var parser = Parser(bytes: [
0x00, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00, 0x01, 0x06, 0x01, 0x60,
0x01, 0x7e, 0x01, 0x7e, 0x03, 0x02, 0x01, 0x00, 0x07, 0x07, 0x01, 0x03,
0x66, 0x61, 0x63, 0x00, 0x00, 0x0a, 0x17, 0x01, 0x15, 0x00, 0x20, 0x00,
0x50, 0x04, 0x7e, 0x42, 0x01, 0x05, 0x20, 0x00, 0x20, 0x00, 0x42, 0x01,
0x7d, 0x10, 0x00, 0x7e, 0x0b, 0x0b
])
while let payload = try parser.parseNext() {
switch payload {
case .header(let version): print("Version: \(version)")
case .customSection(let customSection): print("Custom section: \(customSection)")
case .typeSection(let types): print("Type section: \(types)")
case .importSection(let importSection): print("Import section: \(importSection)")
case .functionSection(let types): print("Function section: \(types)")
case .tableSection(let tableSection): print("Table section: \(tableSection)")
case .memorySection(let memorySection): print("Memory section: \(memorySection)")
case .globalSection(let globalSection): print("Global section: \(globalSection)")
case .exportSection(let exportSection): print("Export section: \(exportSection)")
case .startSection(let functionIndex): print("Start section: \(functionIndex)")
case .elementSection(let elementSection): print("Element section: \(elementSection)")
case .codeSection(let codeSection): print("Code section: \(codeSection)")
case .dataSection(let dataSection): print("Data section: \(dataSection)")
case .dataCount(let count): print("Data count: \(count)")
}
}
```
