2020-06-19Refactor `try_find` a littleJosh Stone-11/+18
The `E` type parameter was unnecessary, so it's now removed. The folding closure now has reduced parametricity on just `T = Self::Item`, rather than the whole `Self` iterator type. There's otherwise no functional change in this.

2020-05-29Add extend_one tracking issue 72631Josh Stone-2/+2
2020-05-29Use a canonical name for extend_reserve(additional)Josh Stone-1/+3
Co-authored-by: David Tolnay <dtolnay@gmail.com>
2020-05-29Add Extend::{extend_one,extend_reserve}Josh Stone-5/+24
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.

2020-05-18Tweak `partition`, `unzip`, `try_find`.Nicholas Nethercote-7/+7
Many default iterator methods use `try_fold` or `fold`, and these ones can too.
2020-05-18Make `fold` standalone.Nicholas Nethercote-13/+20
`fold` is currently implemented via `try_fold`, but implementing it directly results in slightly less LLVM IR being generated, speeding up compilation of some benchmarks. (And likewise for `rfold`.) The commit adds `fold` implementations to all the iterators that lack one but do have a `try_fold` implementation. Most of these just call the `try_fold` implementation directly.
2020-05-16Rollup merge of #72166 - nnethercote:simpler-slice-Iterator-methods, r=cuviperDylan DPC-1/+1
Simpler slice `Iterator` methods These reduce the amount of LLVM IR generated, helping compile times. r? @cuviper
2020-05-13Change `Iterator::nth` to use `self.next()` in a `while` loop.Nicholas Nethercote-1/+1
Currently it uses `for x in self`, which seems dubious within an iterator method. Furthermore, `self.next()` is used in all the other iterator methods.
2020-04-26Use min_specialization in liballocMatthew Jasper-0/+2
- Remove a type parameter from `[A]RcFromIter`. - Remove an implementation of `[A]RcFromIter` that didn't actually specialize anything. - Remove unused implementation of `IsZero` for `Option<&mut T>`. - Change specializations of `[A]RcEqIdent` to use a marker trait version of `Eq`. - Remove `BTreeClone`. I couldn't find a way to make this work with `min_specialization`. - Add `rustc_unsafe_specialization_marker` to `Copy` and `TrustedLen`.

- Added `Iterator::fold_first`, which is like `fold`, but uses the first element in the iterator as the initial accumulator - Includes doc and doctest - Rebase commit; see #65222 for details Co-Authored-By: Tim Vermeulen <tvermeulen@me.com>
2020-03-22Auto merge of #68820 - WaffleLapkin:remove_finished_from_map_while, ↵bors-10/+11
r=LukasKalbertodt Remove `finished` flag from `MapWhile` This PR removes `finished` flag from `MapWhile` as been proposed in https://github.com/rust-lang/rust/pull/66577#discussion_r370958025. This also resolves open questions of the tracking issue (#68537): - `MapWhile` can't implement both + `DoubleEndedIterator` (discussed in https://github.com/rust-lang/rust/pull/66577#discussion_r370947990 and following comments) + `FusedIterator` (this pr removes `finished` flag, so `MapWhile` isn't fused anymore) - Debug output (this pr removes `finished` flag, so there is no question in including it in debug output) r? @Mark-Simulacrum

2020-03-10Rollup merge of #69514 - GuillaumeGomez:remove-spotlight, r=kinnisonMazdak Farrokhzad-1/+0
Remove spotlight I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it. r? @kinnison cc @ollie27

This commit applies rustfmt with default settings to files in src/libcore *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/libcore -name '*.rs' | xargs rustfmt --edition=2018 $ rg libcore outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libcore.
