2020-06-15Rollup merge of #73104 - poliorcetics:explicit-mutex-drop-example, r=dtolnayRalf Jung-0/+54
Example about explicit mutex dropping Fixes #67457. Following the remarks made in #73074, I added an example on the main `Mutex` type, with a situation where there is mutable data and a computation result. In my testing it is effectively needed to explicitly drop the lock, else it deadlocks. r? @dtolnay because you were the one to review the previous PR.

2020-05-03Rollup merge of #71398 - ThinkChaos:feat_refcell_take, r=LukasKalbertodtDylan DPC-1/+1
Add `RefCell::take` Add `RefCell::take` to match `Cell` and `Option`. I also changed a couple of calls to `.replace` to `.take`. Tracking issue is #71395. This is my first contribution, please tell me if there's anything I could improve, thanks!

These are changes that would be needed if we add `#[must_use]` to `Option::map`, per #71484.
2020-04-22More diagnostic items for Clippy usagePhilipp Hansch-0/+1
This adds a couple of more diagnostic items to be used in Clippy. I chose these particular ones because they were the types which we seem to check for the most in Clippy. I'm not sure if the `cfg_attr(not(test))` is needed, but it was also used for `Vec` and a few other types.

2019-12-24Deprecate Error::description for realDavid Tolnay-0/+5
`description` has been documented as soft-deprecated since 1.27.0 (17 months ago). There is no longer any reason to call it or implement it. This commit: - adds #[rustc_deprecated(since = "1.41.0")] to Error::description; - moves description (and cause, which is also deprecated) below the source and backtrace methods in the Error trait; - reduces documentation of description and cause to take up much less vertical real estate in rustdocs, while preserving the example that shows how to render errors without needing to call description; - removes the description function of all *currently unstable* Error impls in the standard library; - marks #[allow(deprecated)] the description function of all *stable* Error impls in the standard library; - replaces miscellaneous uses of description in example code and the compiler.

2019-11-29Format libstd with rustfmtDavid Tolnay-485/+499
This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference

ONCE_INIT is deprecated, and so suggesting it as not only being on par with, but before `Once::new` is a bad idea.
