2021-03-07Add documentation for string->Cow conversionsMichael Howell-0/+33
Mostly, it's just to reassure everyone that these functions don't allocate. Part of #51430
2021-03-07vec![0;4] is a fast path.Giles Cope-22/+20
After much tweaking found a way to get similar asm size as the u8 to_string implementation.

2021-02-23Rollup merge of #82128 - anall:feature/add_diagnostic_items, r=davidtwcoDylan DPC-0/+1
add diagnostic items for OsString/PathBuf/Owned as well as to_vec on slice This is adding diagnostic items to be used by rust-lang/rust-clippy#6730, but my understanding is the clippy-side change does need to be done over there since I am adding a new clippy feature. Add diagnostic items to the following types: OsString (os_string_type) PathBuf (path_buf_type) Owned (to_owned_trait) As well as the to_vec method on slice/[T]

2020-10-18Auto merge of #76885 - dylni:move-slice-check-range-to-range-bounds, r=KodrAusbors-3/+2
Move `slice::check_range` to `RangeBounds` Since this method doesn't take a slice anymore (#76662), it makes more sense to define it on `RangeBounds`. Questions: - Should the new method be `assert_len` or `assert_length`?

2020-09-19Rollup merge of #76525 - fusion-engineering-forks:string-drain, r=dtolnayRalf Jung-1/+35
Add as_str() to string::Drain. Vec's Drain recently [had its `.as_slice()` stabilized](https://github.com/rust-lang/rust/pull/72584), but String's Drain was still missing the analogous `.as_str()`. This adds that. Also improves the Debug implementation, which now shows the remaining data instead of just `"Drain { .. }"`.

2020-09-09Disable AsRef implementations for String's Drain.Mara Bos-14/+15
Since trait implementations cannot be unstable, we should only add them when the as_str feature gets stabilized. Until then, only `.as_str()` is available (behind a feature gate).

Trait implementations effectively can't be #[unstable].

2020-09-04Auto merge of #75207 - dylni:add-slice-check-range, r=KodrAusbors-14/+6
Add `slice::check_range` This method is useful for [`RangeBounds`] parameters. It's even been [rewritten](https://github.com/rust-lang/rust/blob/22ee68dc586440f96b76b32fbd6087507c6afdb9/src/librustc_data_structures/sorted_map.rs#L214) [many](https://github.com/rust-lang/rust/blob/22ee68dc586440f96b76b32fbd6087507c6afdb9/library/alloc/src/vec.rs#L1299) [times](https://github.com/rust-lang/rust/blob/22ee68dc586440f96b76b32fbd6087507c6afdb9/library/core/src/slice/mod.rs#L2441) in the standard library, sometimes assuming that the bounds won't be [`usize::MAX`]. For example, [`Vec::drain`] creates an empty iterator when [`usize::MAX`] is used as an inclusive end bound: ```rust assert!(vec![1].drain(..=usize::max_value()).eq(iter::empty())); ``` If this PR is merged, I'll create another to use it for those methods.
