  • pop is now pop_char

  • iter::Utf16Chars renamed to CharsUtf16 and moved to ustr and ucstr
  • iter::Utf32Chars renamed to CharsUtf32 and moved to ustr and ucstr

  • iter::Utf16CharIndices renamed to CharIndicesUtf16 and moved to ustr and ucstr
  • iter::Utf16CharIndicesLossy renamed to CharIndicesLossyUtf16 and moved to ustr and ucstr

Added

• Added new UTF-encoded string types and associated types:
  • Utf16Str
  • Utf32Str
  • Utf16String
  • Utf32String
• Added macros to convert string literals into const wide string slices:
  • u16str!
  • u16cstr!
  • u32str!
  • u32cstr!
  • widestr!
  • widecstr!
  • utf16str!
  • utf32str!
• Added NUL_TERMINATOR associated constant to U16CStr, U32CStr, U16CString, and U32CString.
• Added DoubleEndedIterator and ExactSizeIterator implementations to a number of iterator types.
• Added new UTF encoding functions alongside existing decode functions:
  • encode_utf8
  • encode_utf16
  • encode_utf32
• Added various methods:
  • repeat on U16Str, U32Str, U16CStr, and U32CStr
  • shrink_to on U16String and U32String

• Added more trait implementations.

Removed

• Breaking Change Functions and types deprecated in 0.5 have been removed.
• Breaking Change The following types and traits, which were implementation details, have been removed. Use the existing non-generic types instead (e.g. use U16Str instead of UStr<u16>).
  • UChar
  • UStr
  • UCStr
  • UString
  • UCString
• Breaking Change Removed IndexMut<RangeFull> trait implementation of U16CString and U32CString. Use the unsafe get_mut method instead, which also supports more ranges.

Fixed

• Breaking Change The iterator returned by U16Str::char_indices and U16CStr::char_indices is now over (usize, Result<char, DecodeUtf16Error>) tuples instead of the reverse order, to better match standard library string iterators. The same is true of U16Str::char_indices_lossy and U16CStr::char_indices_lossy. This matches what was stated in original documentation.
• U32Str::to_string and U32CStr::to_string now only allocate once instead of twice.

0.5.1

Fixed

• Fixed a regression in 0.5.0 where zero-length vectors and strings were incorrectly causing panics in UCString::from_vec and UCString::from_str. Fixes #22.
• Modified an implentation detail in ustr::to_string & ustr::to_string_lossy to remove possibly unsafe behaviour.

0.5.0

Changed

• Breaking Change Renamed a number of types and functions to increase consistency and clarity. This also meant renaming errors to more clearly convey error and trying to be more consistent with name conventions and functionality across types. Check renamed function docs for any changes in functionality, as there have been some minor tweaks (mostly relaxing/removing error conditions and reducing panics). Old names have been deprecated to ease transition and will be removed in a future release. Fixes #18.
  • MissingNulError => error::MissingNulTerminator
  • FromUtf32Error => error::FromUtf32Error
  • NulError => error::ContainsNul

  • U32CString::from_chars_with_nul => from_chars_truncate
  • U32CString::from_char_ptr_with_nul => from_char_ptr_truncate
• Deprecated error types in the crate root. Use the errors directly from error module instead.
• Improved implementations in some areas to reduce unncessary double allocations.
• Improved Debug implementations. No more debugging lists of raw integer values.
• Migrated crate to Rust 2018 edition.
• Minimum supported Rust version is now 1.48.
• Made crate package REUSE compliant.
• Improved documentation and used intra-doc links.

Added

• Added crate-level functions decode_utf16, decode_utf16_lossy, decode_utf32, and decode_utf32_lossy and associated iterators. Note that decode_utf16 is an alias of core::char::decode_utf16, but provided for consistency.
• Added display method to to both UStr and UCStr to display strings in formatting without heap allocations, similar to Path::display. Fixes #20.
• Added more trait implementations, including more index operations and string formatting via Write trait. Fixes #19.
• Added new functions:
  • UStr::from_ptr_mut
  • UStr::from_slice_mut

0.4.2

Fixed

• Fixed compile errors on pre-1.36.0 Rust due to unstable alloc crate. Minimum supported version is Rust 1.34.2, the rust version for Debian stable. Fixes #14

0.4.1

Changed

• Now supports no_std. Added the std and alloc features, enabled by default. U16String,
  U32String, U16CString, and U32CString and their aliases all require the alloc or std
  feature. By @nicbn.

0.4.0

Added

• New U32String, U32Str, U32CString, and U32CStr types for dealing with UTF-32 FFI. These
  new types are roughly equivalent to the existing UTF-16 types.
• WideChar is a type alias to u16 on Windows but u32 on non-Windows platforms.
• The generic types UString, UStr, UCString and UCStr are used to implement the string
  types.

Changed

• Breaking Change Existing wide string types have been renamed to U16String, U16Str,
  U16CString, and U16CStr (previously WideString, WideStr, etc.). Some function have
  also been renamed to reflect this change (wide_str to u16_str, etc.).
• Breaking Change WideString, WideStr, WideCString, and WideCStr are now type aliases
  that vary between platforms. On Windows, these are aliases to the U16 types and are equivalent
  to the previous version, but on non-Windows platforms these alias the new U32 types instead.
  See crate documentation for more details.
