IROX-BITS

Bits & Bobs. No-std/No-alloc bit/byte manipulation of streams.

The main traits provided by this crate are [Bits] (analogous to [std::io::Read]), and [MutBits] (analogous to [std::io::Write]).

Also included are multi-OS wrappers [SeekRead] and [SeekWrite], and a more organic UTF-8 encoding/decoding setup for chars.

This is an Irox foundational crate, it has no external dependencies, is no-std/no-alloc by default (but can be augmented by using the std and alloc features), and many other irox crates extend and augment the functionality contained herein. [irox_structs] is notable as it provides a derivable way to encode/decode structs as a sequence of bytes.

No-STD support:

• The core traits [Bits] and [MutBits] and the majority of the functionality of this crate are available no-std/no-alloc.

Features:

• alloc:
  • Enables the implementation of [Bits] and [MutBits] on the types from the alloc crate:
    • [alloc::string::String]
    • [alloc::vec::Vec]
    • [alloc::collections::VecDeque]
  • Enables the following additional methods:
    • [Bits::read_u8_blob()] -> Vec<u8>
    • [Bits::read_be_u16_blob()]/[Bits::read_le_u16_blob()] -> Vec<u16>
    • [Bits::read_be_u32_blob()]/[Bits::read_le_u32_blob()] -> Vec<u32>
    • [Bits::read_be_u64_blob()]/[Bits::read_le_u64_blob()] -> Vec<u64>
    • [Bits::read_all_vec()] -> Vec<u8>
    • [Bits::read_exact_vec()] -> Vec<u8>
    • [Bits::read_all_str_lossy()] -> [alloc::string::String]
    • [Bits::read_str_sized_lossy()] -> [alloc::string::String]
    • [Bits::read_str_u32_blob()] -> [alloc::string::String]
    • [Bits::read_until()] -> Vec<u8>
    • [Bits::consume_until()] -> ()
    • [MutBits::write_fmt_impl()]
• std:
  • Enables the implementation of [Bits] and [MutBits] on the types from the std crate:
    • [std::fs::File]
  • Also enables the [SeekRead] and [SeekWrite] traits, which wrap and normalize:
    • [std::os::windows::fs::FileExt::seek_read] and [std::os::windows::fs::FileExt::seek_write]
    • [std::os::unix::fs::FileExt:read_at] and [std::os::unix::fs::FileExt::write_at]
  • Enables [std::error::Error] compatibility with [BitsError]
  • Enables (nearly) seamless translation between [std::io::Error] / [BitsError] and [std::io::ErrorKind] / [BitsErrorKind]
