2020-06-25Rollup merge of #72700 - davidtwco:issue-66220-improper-ctypes-declarations, ↵Dylan DPC-0/+2
r=lcnr,varkor `improper_ctypes_definitions` lint Addresses #19834, #66220, and #66373. This PR takes another attempt at #65134 (reverted in #66378). Instead of modifying the existing `improper_ctypes` lint to consider `extern "C" fn` definitions in addition to `extern "C" {}` declarations, this PR adds a new lint - `improper_ctypes_definitions` - which only applies to `extern "C" fn` definitions. In addition, the `improper_ctype_definitions` lint differs from `improper_ctypes` by considering `*T` and `&T` (where `T: Sized`) FFI-safe (addressing #66220). There wasn't a clear consensus in #66220 (where the issues with #65134 were primarily discussed) on the approach to take, but there has [been some discussion in Zulip](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/.2366220.20improper_ctypes.20definitions.20vs.20declarations/near/198903086). I fully expect that we'll want to iterate on this before landing. cc @varkor + @shepmaster (from #19834) @hanna-kruppe (active in discussing #66220), @SimonSapin (#65134 caused problems for Servo, want to make sure that this PR doesn't)

2020-06-24lints: add `improper_ctypes_definitions`David Wood-0/+2
This commit adds a new lint - `improper_ctypes_definitions` - which functions identically to `improper_ctypes`, but on `extern "C" fn` definitions (as opposed to `improper_ctypes`'s `extern "C" {}` declarations). Signed-off-by: David Wood <david@davidtw.co>
2020-06-23Rollup merge of #72876 - TrolledWoods:patch-2, r=Dylan-DPCManish Goregaokar-0/+2
Mention that BTreeMap::new() doesn't allocate I think it would be nice to mention this, so you don't have to dig through the src to look at the definition of new().

2020-06-19Rollup merge of #72709 - LeSeulArtichaut:unsafe-liballoc, r=nikomatsakisManish Goregaokar-257/+387
`#[deny(unsafe_op_in_unsafe_fn)]` in liballoc This PR proposes to make use of the new `unsafe_op_in_unsafe_fn` lint, i.e. no longer consider the body of an unsafe function as an unsafe block and require explicit unsafe block to perform unsafe operations. This has been first (partly) suggested by @Mark-Simulacrum in https://github.com/rust-lang/rust/pull/69245#issuecomment-587817065 Tracking issue for the feature: #71668. ~~Blocked on #71862.~~ r? @Mark-Simulacrum cc @nikomatsakis can you confirm that those changes are desirable? Should I restrict it to only BTree for the moment?

2020-06-15Rollup merge of #72584 - CAD97:stabilize-58957, r=dtolnayRalf Jung-2/+8
Stabilize vec::Drain::as_slice and add `AsRef<[T]> for Drain<'_, T>`. Tracking issue: #58957. Does not stabilize `slice::IterMut::as_slice` yet. cc @cuviper This PR proposes stabilizing just the `vec::Drain::as_slice` part of that tracking issue. My ultimate goal here: being able to use `for<T, I: Iterator<Item=T> + AsRef<[T]>> I` to refer to `vec::IntoIter`, `vec::Drain`, and eventually `array::IntoIter`, as an approximation of the set of by-value iterators that can be "previewed" as by-ref iterators. (Actually expressing that as a trait requires GAT.)

2020-06-09Rename some identifiers in `RawVec` and `libarena`.Nicholas Nethercote-53/+36
- Use `len` more consistently for the number of elements in a vector, because that's the usual name. - Use `additional` more consistently for the number of elements we want to add, because that's what `Vec::reserve()` uses. - Use `cap` consistently rather than `capacity`. - Plus a few other tweaks. This increases consistency and conciseness.
2020-06-09Remove `RawVec::reserve_in_place`.Nicholas Nethercote-39/+6
Also remove a now-unnecessary `placement` argument.

Liballoc impl Mainly code rearrangements
2020-06-08Rollup merge of #72583 - CAD97:vec-iter-asref-slice, r=dtolnayRalf Jung-0/+7
impl AsRef<[T]> for vec::IntoIter<T> Adds `impl<T> AsRef<[T]> for vec::IntoIter<T>`. This mirrors the same trait impl for [`slice::Iter`](https://doc.rust-lang.org/nightly/std/slice/struct.Iter.html). Both types already offer `fn as_slice(&self) -> &[T]`, this just adds the trait impl for `vec::IntoIter`. If/when `fn as_slice(&self) -> &[T]` stabilizes for `vec::Drain` and `slice::IterMut`, they should get `AsRef<[T]>` impls as well. As thus, tangentially related to #58957. My ultimate goal here: being able to use `for<T, I: Iterator<Item=T> + AsRef<[T]>> I` to refer to `vec::IntoIter`, `vec::Drain`, and eventually `array::IntoIter`, as an approximation of the set of by-value iterators that can be "previewed" as by-ref iterators. (Actually expressing that as a trait requires GAT.)

There are two separate `impl<T, Global>` which no special reason, it would be better to merge both of them.

2020-05-30Rollup merge of #72499 - mendess:master, r=dtolnayRalf Jung-0/+41
Override Box::<[T]>::clone_from Avoid dropping and reallocating when cloning to an existing box if the lengths are the same. It would be nice if this could also be specialized for `Copy` but I don't know how that works since it's not on stable. Will gladly look into it if it's deemed as a good idea. This is my first PR with code, hope I did everything right :smile:
2020-05-30Rollup merge of #72162 - cuviper:extend_one, r=Mark-SimulacrumYuki Okushi-0/+126
Add Extend::{extend_one,extend_reserve} This adds new optional methods on `Extend`: `extend_one` add a single element to the collection, and `extend_reserve` pre-allocates space for the predicted number of incoming elements. These are used in `Iterator` for `partition` and `unzip` as they shuffle elements one-at-a-time into their respective collections.
