Changelog

[0.2.0] - 2025-06-17

Added

• Error types now implement core::error::Error
• Str::recode_into - non-allocating variant of recode, returns the Str written
• Str::get_unchecked{,_mut} - unchecked variants of Str::get{,_mut}
• New Encodings:
  • Shift-JIS
  • ISO/IEC 8859-1

Fixed

• UTF-16 BE/LE character boundary detection

Changed

• [Perf] Use a perfect hash function for character encoding
• String::from_bytes and CString::from_std now return OwnValidateError, which provides access to the original bytes.
• Split Utf32 into Utf32LE and Utf32BE. Utf32 is now an alias to the native endian variant.

[0.1.2] - 2024-08-08

Added

• encoding::AlwaysValid, for encodings with no invalid byte patterns
  • Str::from_bytes_infallible{,_mut} - infallible variant of from_bytes{,_mut}
  • String::from_bytes_infallible - infallible variant of from_bytes
  • CStr::from_bytes_{with,til}_nul_valid{,_mut} - no encoding validation variants of equivalent methods.
  • CString::new_valid - no encoding validation variant of new
• Mutable CStr creation methods
  • from_bytes_with_nul_mut
  • from_bytes_til_nul_mut
• rand feature, allows encodings to also function as distributions to generate characters valid for that encoding.
• Added benchmarks
• New Encodings:
  • JIS X 0201
  • JIS X 0208
  • Mac Roman

Fixed

• Win1252 encoding validation mistakenly banned 0x82 instead of 0x81, this has been fixed
• Win1251, Win1252, and JisX0201 had incorrect char_len implementations. They will now return the correct values.

Changed

• Updated README.md, replace lib.rs docs with README.md

[0.1.1] - 2024-05-28

Added

• no_std support
  • Str and CStr are always available
  • String and CString are available on alloc feature
• CString<E> - encoding-specific CString equivalent type
• CStr<E> - encoding-specific CStr equivalent type
  • Unlike CStr, CStr<E> will deref to Str<E>
• New Encodings:
  • ISO/IEC 8859-2
  • ISO/IEC 8859-15

[0.1.0] - 2024-05-25

Initial release. Adds core types and the most common encodings.

Added

• Encoding - trait representing a generic encoding such as UTF-8 or Windows-1252
• String<E> - encoding-specific String equivalent type
  • String<Utf8> is free to convert from an std::string::String
• Str<E> - encoding specific str type
  • Str<Utf8> is free to convert from a str
• New Encodings:
  • ASCII
  • ASCII Extended
    • Variant of ASCII that supports all byte values
  • UTF{8, 16LE, 16BE, 32}
  • Windows-{1251, 1252}
  • Windows-1252 Loose
    • Variant of 1252 that supports all byte values
