/*! ## Bit-level reading and writing `std::io::{Read, Write}` only allow reading and writing on the byte-level. This is not sufficient when working with protocols that use single bits or use structs that are not multiples of 8 bits in size. This crate provides wrappers for reading and writing, enabling bit-level I/O on any object implementing `std::io::Read`/`std::io::Write`. The wrappers are modeled after `std::io::BufReader` and `std::io::BufWriter`, so the semantics and interface should be familiar and robust. This crate is a minimal low-level abstraction focusing on bit-level I/O. I recommend using this crate together with `endio` for a higher level of abstraction and ergonomics. However, this crate is completely independent from `endio`, and can be used standalone if you're only looking for `std::io` with bit support. ### Goals of this crate - Reading and writing of single bits. - Reading and writing of bits that aren't a multiple of 8. - Reading and writing even if the underlying object is bitshifted. ### Non-goals of this crate - Any data type (de-)serialization. If you need this, use `endio` in combination with this crate. - Any endianness conversion/distinction. If you need this, use `endio` in combination with this crate. ### Comparison with other crates Bit-level I/O is a common problem, and there are numerous crates on crates.io attempting to provide solutions. However, I haven't been able to find one that is completely satisfactory. Here's a list of related crates and how they differ from this one: - `av-bitstream` - Includes (de-)serialization and endianness. The entire crate is undocumented. - `bit-io` - Does not implement `std::io::{Read, Write}` on its abstractions, thus not being suitable for code requiring these traits. - `bitio` - Only has support for reading. - `bitstream`, `bitstream_reader`, `bitter` - Only have support for reading. Include deserialization and endianness instead of being a low-level abstraction. - `bitstream-io` - Includes (de-)serialization and endianness. Includes Huffman trees for some reason. Does not implement `std::io::{Read, Write}` on its abstractions. - `bitstream-rs` - Only has support for reading and writing single bits. Does not implement `std::io::{Read, Write}` on its abstractions. - `bitreader` - Only has support for reading. Includes deserialization in forced big endian, no little endian support. Therefore there is an opportunity to improve on the current library situation, which I hope to address through this crate. */ mod read; mod write; pub use self::read::*; pub use self::write::*;
