In accordance with [collections reform part 2][rfc] this macro has been moved to an external [bitflags crate][crate] which is [available though crates.io][cratesio]. Inside the standard distribution the macro has been moved to a crate called `rustc_bitflags` for current users to continue using. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0509-collections-reform-part-2.md [crate]: https://github.com/rust-lang/bitflags [cratesio]: http://crates.io/crates/bitflags The major user of `bitflags!` in terms of a public-facing possibly-stable API today is the `FilePermissions` structure inside of `std::io`. This user, however, will likely no longer use `bitflags!` after I/O reform has landed. To prevent breaking APIs today, this structure remains as-is. Current users of the `bitflags!` macro should add this to their `Cargo.toml`: bitflags = "0.1" and this to their crate root: #[macro_use] extern crate bitflags; Due to the removal of a public macro, this is a: [breaking-change]
