Bump enumflags2 from 0.7.5 to 0.7.7

[dependabot]

Bumps enumflags2 from 0.7.5 to 0.7.7.

Release notes

Sourced from enumflags2's releases.

Release 0.7.7

This release fixes a soundness issue in the make_bitflags! macro. Previously, code like this was accepted:

#[bitflags]
#[repr(u8)]
#[derive(Copy, Clone, Debug)]
enum Test {
    A = 1,
    B = 2,
}
impl Test {
const C: u8 = 69;
}
fn main() {
let x = make_bitflags!(Test::{C});
}

Iterating over x would then create values of Test with bit patterns that don't correspond to any of the variants, which is undefined behavior.

This bug has been introduced in 0.7.0, together with the make_bitflags! macro itself.

I don't think it is likely that this was actually present in anyone's code, but in an abundance of caution, I have yanked all affected versions.

RUSTSEC advisory pending.

Release 0.7.6

• Update to syn 2.0 (thanks to @​mwkmwkmwk)
• Bump MSRV to 1.56.0 to support the above
• Update crate metadata to compensate for gender drift :3
