+# `wasmparser`: A WebAssembly Binary Parser

+
+A simple, event-driven library for parsing WebAssembly binary files (or
+streams).
+
+The library reports events as they happen and only stores parsing information
+for a brief period of time, making it fast and memory-efficient. The
+event-driven model, however, has some drawbacks. If you need random access to
+the entire WebAssembly data-structure, this is not the right library for
+you. You could however, build such a data-structure using this library.
+
+To get started, create a
+[`Parser`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html)
+using
+[`Parser::new`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.new)
+and then follow the examples documented for
+[`Parser::parse`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.parse)
+or
+[`Parser::parse_all`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.parse_all).
