Lot’s of reported regressions. I haven’t looked at them yet.

Had a quick look through to find the relevant issues:

Beta:

• pod/immeta/rcon/elf/nue - read_exact - https://github.com/rust-lang/rust/issues/28126
• chipmunk/chipmunk-sys) - extern fn with 6+ args - https://github.com/rust-lang/rust/issues/28559
• aurelius/sprs - lifetime problems
• cuckoofilter - deprecated method - removed in https://github.com/rust-lang/rust/pull/27684

Nightly:

• gfx-pipeline/backend - feature gating import problem - https://github.com/rust-lang/rust/issues/28075
• graph - task log is empty? crate does nothing anyway.
• pinyin - lifetime problem
• cudd-sys/ao - invalid attributes - https://github.com/rust-lang/rust/pull/28650

Maybe https://github.com/rust-lang/rust/pull/28560 be backported to beta?

Other than that, I didn’t see any surprises looking through the regressions.

Awesome! Thank you for doing the analysis @Eljay @eefriedman.

The cuckoofilter breakage was because of a bug that allowed it to import in a use list an unstable feature, which is fixed by https://github.com/rust-lang/rust/pull/28364

aurelius/sprs - lifetime problems

is this related to any known issue?

[seanmonstar]

Even though it was allowed because of a bug, fixing said bug is a breaking change. I’d personally expect such changes not to happen, considering the "commitment to stability".

It’s just a missing bound. Not sure why this particular formulation triggers an error, as opposed to an RFC 1214 warning. Reduces to:

use std::ops::Deref;
pub struct CsMat<N, DataStorage> where DataStorage: Deref<Target=[N]> {
    _data: DataStorage,
}
pub struct ChunkOuterBlocks<'a, N> {
    _mat: CsMat<N, &'a [N]>,
}
fn main(){}

Understood, thanks.
