Adding of new reference files wasn't handled correctly. It was trying to
read a file that didn't exist yet.
Instead of unwrapping, we now treat a missing reference file as empty
(`Vec::new`). This makes the following conditional work. We then also
have to re-read the reference file after it was being copied. This
second read is technically the same as in the old shell script, but
wasn't really obvious. The shell script did a `-s` test which reads the
file.
Add the "async" and "promise" doc aliases to `core::future::Future`
Adds the "async" and "promise" doc aliases to `core::future::Future`. This enables people who search for "async" or "promise" to find `Future`, which is Rust's core primitive for async programming. Thanks!
Stabilize or_insert_with_key
Stabilizes the `or_insert_with_key` feature from https://github.com/rust-lang/rust/issues/71024. This allows inserting key-derived values when a `HashMap`/`BTreeMap` entry is vacant.
The difference between this and `.or_insert_with(|| ... )` is that this provides a reference to the key to the closure after it is moved with `.entry(key_being_moved)`, avoiding the need to copy or clone the key.
passes: prohibit invalid attrs on generic params
Fixes#78957.
This PR modifies the `check_attr` pass so that attribute placement on generic parameters is checked for validity.
r? `@lcnr`
Register nodes that we've reused from the previous session explicitly
with `OnDiskCache`. Previously, we relied on this happening as a side
effect of accessing the nodes in the `PreviousDepGraph`. For the sake of
performance and avoiding unintended side effects, register explictily.
Continue String to Symbol conversion in rustdoc (2)
Follow-up of #80119.
This is the last one (and I actually expected more conversions but seems like it was the last one remaining...).

Renamed the good first issue label in CONTRIBUTING.md
Follow up from #6468

rust-clippy/CONTRIBUTING.md:Some issues are easier than others. The [`good first issue`] label can be used to find the easy issues.
rust-clippy/CONTRIBUTING.md:[`E-medium`] issues are generally pretty easy too, though it's recommended you work on an [`good first issue`]

r? `@flip1995`
This is elegant but a bit of a perf gamble. That said, or-patterns
rarely have many branches and it's easy to optimize or revert if we ever
need to. In the meantime simpler code is worth it.
Edit formatting in Rust Prelude docs
Use consistent punctuation and capitalization in the list of things re-exported in the prelude.
Also adds a (possibly missing) word.
