Merge main onto trusty-main Need to align the branches in order to use the same set of autogenerated les.mk files to build the Rust crates used in Trusty. Bug: 281857510 Change-Id: I23e6db423920c52c66e52bf12087fc36b4d02784
A Rust macro to generate structures which behave like a set of bitflags
Add this to your Cargo.toml
:
[dependencies] bitflags = "2.3.2"
and this to your source code:
use bitflags::bitflags;
Generate a flags structure:
use bitflags::bitflags; // The `bitflags!` macro generates `struct`s that manage a set of flags. bitflags! { #[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Hash)] struct Flags: u32 { const A = 0b00000001; const B = 0b00000010; const C = 0b00000100; const ABC = Self::A.bits() | Self::B.bits() | Self::C.bits(); } } fn main() { let e1 = Flags::A | Flags::C; let e2 = Flags::B | Flags::C; assert_eq!((e1 | e2), Flags::ABC); // union assert_eq!((e1 & e2), Flags::C); // intersection assert_eq!((e1 - e2), Flags::A); // set difference assert_eq!(!e2, Flags::A); // set complement }
The minimum supported Rust version is documented in the Cargo.toml
file. This may be bumped in minor releases as necessary.
