Improve `std:🧵:available_parallelism` docs _Tracking issue: https://github.com/rust-lang/rust/issues/74479_ This PR reworks the documentation of `std:🧵:available_parallelism`, as requested [here](https://github.com/rust-lang/rust/pull/89324#issuecomment-934343254). ## Changes The following changes are made: - We've removed prior mentions of "hardware threads" and instead centers the docs around "parallelism" as a resource available to a program. - We now provide examples of when `available_parallelism` may return numbers that differ from the number of CPU cores in the host machine. - We now mention that the amount of available parallelism may change over time. - We make note of which platform components we don't take into account which more advanced users may want to take note of. - The example has been updated, which should be a bit easier to use. - We've added a docs alias to `num-cpus` which provides similar functionality to `available_parallelism`, and is one of the most popular crates on crates.io. --- Thanks! r? `@BurntSushi` |
