Optimized bit-level Reader and Writer for Go, enabling efficient reading and writing of arbitrary bit lengths.
bitio is a Go package that provides optimized bit-level Reader and Writer types, allowing developers to read and write data at arbitrary bit lengths rather than just whole bytes. It solves the problem of fine-grained bit manipulation required for implementing compression algorithms, binary protocols, and other low-level data processing tasks.
Go developers working on compression algorithms, binary protocol implementations, or any low-level data processing that requires precise bit-level I/O operations.
Developers choose bitio for its performance and flexibility, offering a clean API that integrates seamlessly with Go's standard I/O interfaces while efficiently handling the complexities of bit-level operations, including dual-level byte and bit views and convenience methods for error handling.

Provides ReadBits() and WriteBits() methods for arbitrary bit lengths (1-64), enabling precise control essential for compression algorithms and binary protocols, as demonstrated in the README's bit extraction examples.
Includes ReadBool() and WriteBool() for single-bit reads/writes, specifically designed for Huffman coding and decision trees, reducing overhead for frequent bit operations.
Simultaneously offers bit-level and byte-level views (implementing io.Reader, io.Writer, etc.) with alignment control via Align(), allowing seamless integration with standard Go I/O for mixed operations.
TryReadBits() and TryWriteBits() methods store errors in TryError fields for deferred checking, simplifying chained operations and reducing boilerplate, as shown in the README's error handling examples.
Uses highest-bits-first order only, which may not be compatible with protocols or formats that require little-endian bit sequencing, limiting flexibility without manual workarounds.
Byte-level operations (Read/Write) can be slower when not aligned to byte boundaries, as bits must be assembled or spread across multiple bytes, as noted in the README.
Lacks support for endianness handling, common data structures, or compression codecs, requiring developers to implement these separately, which can increase development time for complex use cases.
