| //! A simple event-driven library for parsing WebAssembly binary files |
| //! (or streams). |
| //! |
| //! The parser library reports events as they happen and only stores |
| //! parsing information for a brief period of time, making it very 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`] using [`Parser::new`] and then follow |
| //! the examples documented for [`Parser::parse`] or [`Parser::parse_all`]. |
