Currently mirrors are stored in the rust-lang-ci2 S3 bucket along with CI toolchains. This is problematic for multiple reasons: - CI IAM credentials are allowed to both edit and delete those files. A malicious user gaining access to those credentials would be able to change our mirrored dependencies, possibly backdooring the compiler. - Contents of the rust-lang-ci2 bucket are disposable except for the mirrors' content. When we implement backups for S3 buckets we'd have to replicate just that part of the bucket, complicating the backup logic and increasing the chance of mistakes. A standalone bucket will be way easier to backup. This commit switches our CI to use the new rust-lang-ci-mirrors bucket.

This commit prohibits return position `impl Trait` types that "inherit lifetimes" from the parent scope. The intent is to forbid cases that are challenging until they can be addressed properly.
We now always make fresh lifetimne parameters for all elided
lifetimes, whether they are in the inputs or outputs. But then
we generate `'_` in the case of elided lifetimes from the outputs.
Example:
```rust
async fn foo<'a>(x: &'a u32) -> &u32 { .. }
```
becomes
```rust
type Foo<'a, 'b> = impl Future<Output = &'b u32>;
fn foo<'a>(x: &'a u32) -> Foo<'a, '_>
```

…imes, r=nikomatsakis typeck: Prohibit RPIT types that inherit lifetimes Part of rust-lang#61949. This PR prohibits return position `impl Trait` types that "inherit lifetimes" from the parent scope. The intent is to forbid cases that are challenging until they can be addressed properly. cc @nikomatsakis
…s, r=nikomatsakis `async fn` lifetime elision tests Add `async fn` version of the tests in rust-lang#61207 per the first checkbox in rust-lang#62121 (comment). Works towards resolving blockers in rust-lang#63209. r? @nikomatsakis cc @cramertj
Implement Clone, Display for ascii::EscapeDefault This will mimic the same behaviour as the `char` version; `Display`ing the iterator will give its string representation without advancing it.
syntax: account for CVarArgs being in the argument list. Fixes rust-lang#63430 by testing for `1` argument (the `CVarArgs` itself) instead of `0`. Note that the error has basically been impossible to trigger since the change that caused rust-lang#63430, so perhaps we need an audit of untested errors. Also, this check probably belongs in AST validation/HIR lowering, but I'd rather fix it in place for now. r? @petrochenkov cc @dlrobertson

…lexcrichton ci: move mirrors to their standalone bucket Currently mirrors are stored in the rust-lang-ci2 S3 bucket along with CI toolchains.

…inaryheap, r=Centril Document `From` trait for `BinaryHeap` This PR solves part of rust-lang#51430.
