Introduction to the WebAssembly Binary Toolkit

Overview

The Rust compiler chain converts Rust code into WebAssembly binary. But the generated binaries are both size- and performance-optimized. It’s difficult to understand, debug, and validate binary code (it is a bunch of hexadecimal numbers). Converting WebAssembly binary back into the original source code is very difficult. WebAssembly Binary Toolkit (WABT) helps to convert WebAssembly binary into a human-readable format, such as the WebAssembly text (WAST) format or C-native code.
