Add unstable attribute to BTreeMap-related allocator generics

2025-09-20T04:32:15+00:00

Although these types aren't directly constructable externally, since they're pub, I think this omission was an oversight.

Rollup merge of #144871 - Kivooeo:btree_entry_insert-stabilize, r=jhpratt

2025-09-17T04:56:42+00:00

Stabilize `btree_entry_insert` feature This stabilises `btree_map::VacantEntry::insert_entry` and `btree_map::Entry::insert_entry`, following the FCP in [tracking issue](https://github.com/rust-lang/rust/issues/65225). New stable API: ```rust impl<'a, K: Ord, V, A: Allocator + Clone> Entry<'a, K, V, A> { pub fn insert_entry(self, value: V) -> OccupiedEntry<'a, K, V, A>; } impl<'a, K: Ord, V, A: Allocator + Clone> VacantEntry<'a, K, V, A> { pub fn insert_entry(mut self, value: V) -> OccupiedEntry<'a, K, V, A>; } ``` (FCP ended almost a year ago, so if it's needed for process we could rerun it) Closes: https://github.com/rust-lang/rust/issues/65225

Add `BTreeSet` entry APIs to match `HashSet`

2024-11-27T18:51:24+00:00

* `fn get_or_insert(&mut self, value: T) -> &T` * `fn get_or_insert_with(&mut self, value: &Q, f: F) -> &T` * `fn entry(&mut self, value: T) -> Entry<'_, T, A>` (+ `Entry` APIs)

btree: add `{Entry,VacantEntry}::insert_entry`

2024-11-14T19:41:55+00:00

This matches the recently-stabilized methods on `HashMap` entries. I've reused tracking issue #65225 for now, but we may want to split it.

Reformat using the new identifier sorting from rustfmt

Reformat `use` declarations.

2024-07-28T22:26:52+00:00

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

Fix doc nits

2024-07-26T12:26:33+00:00

Many tiny changes to stdlib doc comments to make them consistent (for example "Returns foo", rather than "Return foo", per RFC1574), adding missing periods, paragraph breaks, backticks for monospace style, and other minor nits. https://github.com/rust-lang/rfcs/blob/master/text/1574-more-api-documentation-conventions.md#appendix-a-full-conventions-text
