2018-01-24Auto merge of #47299 - cramertj:unsafe-placer, r=alexcrichtonbors-1/+1
Make core::ops::Place an unsafe trait Consumers of `Place` would reasonably expect that the `pointer` function returns a valid pointer to memory that can actually be written to.
2018-01-20Rename std::ptr::Shared to NonNullSimon Sapin-5/+5
`Shared` is now a deprecated `type` alias. CC https://github.com/rust-lang/rust/issues/27730#issuecomment-352800629

2017-12-16Move PhantomData<T> from Shared<T> to users of both Shared and #[may_dangle]Simon Sapin-0/+3
After discussing [1] today with @pnkfelix and @Gankro, we concluded that it’s ok for drop checking not to be much smarter than the current `#[may_dangle]` design which requires an explicit unsafe opt-in. [1] https://github.com/rust-lang/rust/issues/27730#issuecomment-316432083

2017-11-03Remove unused AsciiExt imports and fix tests related to ascii methodsLukas Kalbertodt-2/+0
Many AsciiExt imports have become useless thanks to the inherent ascii methods added in the last commits. These were removed. In some places, I fully specified the ascii method being called to enforce usage of the AsciiExt trait. Note that some imports are not removed but tagged with a `#[cfg(stage0)]` attribute. This is necessary, because certain ascii methods are not yet available in stage0. All those imports will be removed later. Additionally, failing tests were fixed. The test suite should exit successfully now.

2017-09-20Auto merge of #44355 - Xaeroxe:optimize_drain_filter, r=alexcrichtonbors-1/+7
Optimize drain_filter This PR cuts out two copies from each iteration of `drain_filter` by exchanging the swap operation for a copy_nonoverlapping function call instead. Since the data being swapped is not needed anymore we can just overwrite it instead.

2017-08-15Auto merge of #43245 - Gankro:drain-filter, r=sfacklerbors-0/+113
Add Vec::drain_filter This implements the API proposed in #43244. So I spent like half a day figuring out how to implement this in some awesome super-optimized unsafe way, which had me very confident this was worth putting into the stdlib. Then I looked at the impl for `retain`, and was like "oh dang". I compared the two and they basically ended up being the same speed. And the `retain` impl probably translates to DoubleEndedIter a lot more cleanly if we ever want that. So now I'm not totally confident this needs to go in the stdlib, but I've got two implementations and an amazingly robust test suite, so I figured I might as well toss it over the fence for discussion.

2017-07-26Rollup merge of #43455 - QuietMisdreavus:extend-spec-docs, r=steveklabnikMark Simulacrum-0/+6
add a note to Vec's Extend<&T> impl about its slice specialization From the regular documentation view, it's not at all apparent that [this specialization](https://github.com/rust-lang/rust/blob/5669c9988f50788b5ab5dee2d4538519d4e5663d/src/liballoc/vec.rs#L1879-L1891) exists for `slice::Iter`. This adds a documentation blurb to the Extend impl itself to note that this optimization exists.

2017-07-03Document unintuitive argument order for Vec::dedup_by relationAnders Kaseorg-4/+7
When trying to use dedup_by to merge some auxiliary information from removed elements into kept elements, I was surprised to observe that vec.dedup_by(same_bucket) calls same_bucket(a, b) where b appears before a in the vector, and discards a when true is returned. This argument order is probably a bug, but since it has already been stabilized, I guess we should document it as a feature and move on. (Vec::dedup also uses == with this unexpected argument order, but I figure that’s not important since == is expected to be symmetric with no side effects.)

2017-06-23Removed as many "```ignore" as possible.kennytm-1/+1
Replaced by adding extra imports, adding hidden code (`# ...`), modifying examples to be runnable (sorry Homura), specifying non-Rust code, and converting to should_panic, no_run, or compile_fail. Remaining "```ignore"s received an explanation why they are being ignored.
