2016-07-16Rollup merge of #34838 - steveklabnik:gh33677, r=alexcrichtonGuillaume Gomez-5/+8
Fix up documentation around no_std 1. Fix the sections in the book to have the correct signatures. I've also marked them as `ignore`; there's no way to set the `no_std` feature for libc, so it pulls in the stdlib, so this wasn't even testing the actual thing it was testing. Better to just ignore. 2. Correcting libcore's docs for factual inaccuracy, and add a note about language items. Fixes #33677 r? @alexcrichton

2016-07-12std: Clean out deprecated APIsAlex Crichton-33/+0
This primarily removes a lot of `sync::Static*` APIs and rejiggers the associated implementations. While doing this it was discovered that the `is_poisoned` method can actually result in a data race for the Mutex/RwLock primitives, so the inner `Cell<bool>` was changed to an `AtomicBool` to prevent the associated data race. Otherwise the usage/gurantees should be the same they were before.

2016-07-09Auto merge of #34365 - petrochenkov:deferr, r=eddybbors-1/+1
Some more pattern cleanup and bugfixing The next part of https://github.com/rust-lang/rust/pull/34095 The most significant fixed mistake is definitions for partially resolved associated types not being updated after full resolution. ``` fn f<T: Fn()>(arg: T::Output) { .... } // <- the definition of T::Output was not updated in def_map ``` For this reason unstable associated types of stable traits, like `FnOnce::Output`, could be used in stable code when written in unqualified form. Now they are properly checked, this is a **[breaking-change]** (pretty minor one, but a crater run would be nice). The fix is not to use unstable library features in stable code, alternatively `FnOnce::Output` can be stabilized. Besides that, paths in struct patterns and expressions `S::A { .. }` are now fully resolved as associated types. Such types cannot be identified as structs at the moment, i.e. the change doesn't make previously invalid code valid, but it improves error diagnostics. Other changes: `Def::Err` is supported better (less chances for ICEs for erroneous code), some incorrect error messages are corrected, some duplicated error messages are not reported, ADT definitions are now available through constructor IDs, everything else is cleanup and code audit.

2016-07-06feat: reinterpret `precision` field for stringsEvgeny Safronov-7/+11
This commit changes the behavior of formatting string arguments with both width and precision fields set. Documentation says that the `width` field is the "minimum width" that the format should take up. If the value's string does not fill up this many characters, then the padding specified by fill/alignment will be used to take up the required space. This is true for all formatted types except string, which is truncated down to `precision` number of chars and then all of `fill`, `align` and `width` fields are completely ignored. For example: `format!("{:/^10.8}", "1234567890);` emits "12345678". In the contrast Python version works as the expected: ```python >>> '{:/^10.8}'.format('1234567890') '/12345678/' ``` This commit gives back the `Python` behavior by changing the `precision` field meaning to the truncation and nothing more. The result string *will* be prepended/appended up to the `width` field with the proper `fill` char. However, this is the breaking change. Also updated `std::fmt` docs about string precision.

prefer `if let` to match with `None => {}` arm in some places This is a spiritual succesor to #34268 / 8531d581, in which we replaced a number of matches of None to the unit value with `if let` conditionals where it was judged that this made for clearer/simpler code (as would be recommended by Manishearth/rust-clippy's `single_match` lint). The same rationale applies to matches of None to the empty block. ---- r? @jseyfried
