std: allow after-main use of synchronization primitives2024-11-18T16:55:36+00:00joboetjonasboettiger@icloud.com2024-11-07T16:13:33+00:00urn:sha1:5a856b82f3a1bf335e0e62d92c800d8436977af1
By creating an unnamed thread handle when the actual one has already been destroyed, synchronization primitives using thread parking can be used even outside the Rust runtime.
This also fixes an inefficiency in the queue-based `RwLock`: if `thread::current` was not initialized yet, it will create a new handle on every parking attempt without initializing `thread::current`. The private `current_or_unnamed` function introduced here fixes this.

This commit adds the `downgrade` method onto the inner `RwLock` queue
implementation.
There are also a few other style patches included in this commit.

modify queue implementation documentation2024-11-16T17:31:13+00:00Connor Tsuiconnor.tsui20@gmail.com2024-10-25T18:54:43+00:00urn:sha1:31e35c2131f0b71a7d2cdc3b515d1a22f5f3b61d
This commit only has documentation changes and a few things moved around
the file. The very few code changes are cosmetic: changes like turning a
`match` statement into an `if let` statement or reducing indentation for
long if statements.
This commit also adds several safety comments on top of `unsafe` blocks
that might not be immediately obvious to a first-time reader.
Code "changes" are in:
- `add_backlinks_and_find_tail`
- `lock_contended`
A majority of the changes are just expanding the comments from 80
columns to 100 columns.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.
