Document `label_break_value` in the reference

Or "breakable expressions"?

RFC: Field projection

The trait suggested here isn't actually implementable: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=23e3e48fbc2816cf3f6460bceeba6dd2 Probably it should have an extra lifetime param: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=23e3e48fbc2816cf3f6460bceeba6dd2 ```rust pub trait FieldProjecting

I experimented the field pointer idea before, and I find it not satisfactory because there are no way to distinguish two fields of the same type in the same struct...

Connection refused while initiating application

I have no immediate clue of what's wrong there. Maybe try deleting files in /tmp and try again as WSL doesn't clean up the temporary files automatically.

async_std::sync::Mutex is too heavy

I did a few experiments, and I think I got an idea that can reduce `async_std::sync::Mutex` to the size of usize and makes it allocation-free when there isn't contention. Here's...

async_std::sync::Mutex is too heavy

The linked list nodes are allocated on the heap, for the benefits of a stable address. Linked list has an extra benefit of guaranteed `O(1)` insertion/removal (slab uses `Vec`, which...

async_std::sync::Mutex is too heavy

> If you just use [futures_intrusive::sync::Mutex](https://docs.rs/futures-intrusive/0.2.0/futures_intrusive/sync/type.Mutex.html) you get your parking-lot backed small mutex without any need for heap allocations - and even without the need to write the code yourself...
