Rust bitfields and enumerations C++ style The bitfield crate @Boiethios mentioned is kind of what I wanted. I created my own first macro crate bitfield which allows me to write the following: #[bitfield::bitfield(32)] struct Styles { #[... ...
The solution is to actually store the value as a u8, then use constants to store the value of each flag. This can be cumbersome, but thankfully the bitflags crate wraps all the boilerplate up in a macro for you. Here is an example how you would create your struct using bitflags:bitf...
To import the macro, we need to use `#[macro_use]` above the `extern crate` definition: @@ -112,23 +112,23 @@ Now we can model the various flags: ```rust bitflags! { pub flags EntryFlags: u64 { const PRESENT = 1 << 0, const WRITABLE = 1 << 1, const USER_ACCESSIBLE =...
Rust中的enum不打算用作位标志。PublicFlags可以 * 仅 * 接受枚举中给定的值(而不是组合)。例如,...
Motivation Inspiration for writing thisbitflagslibrary I got from the homonymous Rust's crate that you may findhere. Some people may ask:Why not just useenum classand assign binary literals? Following example presents usingenum classwithstd::uint8_tas underlying type (so that max number of flag...
