v0.7.0

Release Notes: 0.7.0 (2020-10-18)

• Tons of macro generated code hygiene improvements for both #[bitfield] and #[derive(BitfieldSpecifier)].
• #[bitfield] now produces with_{} and with_{}_checked methods that take self and return Self. (Thanks @lkolbly)
  • This is useful for building up your bitfields without the need of a mutable reference.
• #[bitfield] generated getters now are the same identifiers as their fields. (Thanks @Qyriad)
  • Previously for a field a it generated fn get_a(..) but now it generates fn a(..) instead.
• #[bitfield] now properly inherits visibility modifiers for all fields onto their generated getters and setters. (Thanks @WorldSEnder)
• Remove TryFrom implementation from #[bitfield] generated structs since it never was really safe.
  • It didn't check for invalid bit patterns and thus could trigger undefined behaviour.
• The #[bitfield] generated new constructor is now a const fn.
• Rename the #[bitfield] generated to_bytes to as_bytes.
  • Also it now returns a refernce to an array, e.g. &[u8; N] instead of a slice.
• The #[bitfield] macro now generates an unsafe fn from_bytes_unchecked that allows constructing from raw bytes.
  • This is meant as an unsafe replacement for the removed TryFrom implementation.
  • We plan to create safer alternatives in future updates.
• Updated all benchmarks to use the criterion crate.
• Fixed a parsing bug that enum variant names sometimes could clash with Rust keywords. (Thanks @Qyriad)
• Fixed a bug that caused getters to sometimes read with extra invalid bits. (Thanks @crzysdrs)
• Fixed an issue that was caused by single bit manipulations. (Thanks @crzysdrs)
