Crate parsenic 

A simple no-std/no-alloc I/O and parsing crate

The main two traits for parsing are Read and Write, implemented by Reader, which reads from a fixed-size slice of bytes, and Writer, which writes to a fixed-size slice of bytes. The Read and Write traits are designed to be extended with extension traits, using traitful::extend.

Extension traits for big-endian an little-endian parsing are provided in this crate as well; be::Read, be::Write, le::Read, le::Write. When importing a Read or Write extension trait, using as _ will avoid namespace conflicts.

Synchronous and Asynchronous

The Read and Write traits are synchronous by design. This makes it simple to read and write on in-memory data without touching I/O. For I/O bound reading and writing, there are the io::Source and io::Destination traits which work by buffering the bytes to be sent on an io::Sender or received on an io::Receiver.

Features

Some non-default features can enable unstable (no API stability guarantees) functionality.

• unstable-io: Bumps MSRV to 1.84, enables the io module
• unstable-error: Bumps MSRV to 1.81, implements Error for error types
