1.0.5

  • Use compiletest_rs flags supported by stable toolchain (#171)

  • Put the user provided attributes first (#173)

  • Make bitflags methods const on newer compilers (#175)

1.0.4

  • Support Rust 2018 style macro imports (#165)

    use bitflags::bitflags;

1.0.3

  • Improve zero value flag handling and documentation (#157)

1.0.2

  • 30% improvement in compile time of bitflags crate (#156)

  • Documentation improvements (#153)

  • Implementation cleanup (#149)

1.0.1

  • Add support for pub(restricted) specifier on the bitflags struct (#135)
  • Optimize performance of all() when called from a separate crate (#136)

1.0.0

  • [breaking change] Macro now generates associated constants (#24)

  • [breaking change] Minimum supported version is Rust 1.20, due to usage of associated constants

  • After being broken in 0.9, the #[deprecated] attribute is now supported again (#112)

  • Other improvements to unit tests and documentation (#106 and #115)

How to update your code to use associated constants

Assuming the following structure definition:

bitflags! {
  struct Something: u8 {
     const FOO = 0b01,
     const BAR = 0b10
  }
}

In 0.9 and older you could do:

let x = FOO.bits | BAR.bits;

Now you must use:

let x = Something::FOO.bits | Something::BAR.bits;

0.9.1

  • Fix the implementation of Formatting traits when other formatting traits were present in scope (#105)

0.9.0

  • [breaking change] Use struct keyword instead of flags to define bitflag types (#84)

  • [breaking change] Terminate const items with semicolons instead of commas (#87)

  • Implement the Hex, Octal, and Binary formatting traits (#86)

  • Printing an empty flag value with the Debug trait now prints "(empty)" instead of nothing (#85)

  • The bitflags! macro can now be used inside of a fn body, to define a type local to that function (#74)

0.8.2
