v0.9.0

Updated

• Breaking change: Lexer::into_inner() returns a &str.
• Breaking change: Lexer::tokenize() restores the panic behavior in
  previous versions. If the position argument is greater than the input's byte length,
  then a panic occurs. The position argument is also immediately checked to be
  at a UTF-8 character boundary instead of waiting for a panic in a subsequent
  function call.
• Breaking change: Spaces around properties like attribute names, attribute
  values, and processing instructions are trimmed in their representations.
• Breaking change: Minimum supported Rust version is now 1.71.0.
• Renamed Lexer into Reader. Lexer is still exposed as a hidden alias but will
  be removed in a future version.
• Token::ty() is made const.

Removed

• Remove From and from_str implementations from token
  and property types. Due to possible future implementation changes and
  undocumented invariants, the ability to directly construct a type is removed.
• Remove as_str(), as_bytes(), as_str_unchecked(),
  and into_inner() implementations for Attributes and Attribute. Both are opaque
  types where the internal data may change.

Deprecated

• Deprecated from_slice_unchecked() on Lexer. Use core::str::from_utf8_unchecked()
  on the byte slice and then pass into Reader::from_str() if the byte slice is
  guaranteed to be a valid UTF-8 string.

Added

• Most functions are const on the token and property types. Refactored most
  token and property type function implementations to be const compatible.
• Add Reader::parse() as a const alternative function to
  Reader::tokenize(). The function does not mutate the position argument so the
  position must be re-calculated like pos += token.len() in the calling code.
• Add Attributes.parse() as a const function to parse the attributes like
  Reader::parse().
• Add Display implementations to Token and token types.
• Derive PartialOrd, Ord, and Hash for Token and Ty.
• Add len() method to token types.
