2024-12-22Specify only that duplicates are discarded, not the order.Kevin Reid-4/+5
2024-12-21Document collection `From` and `FromIterator` impls that drop duplicate keys.Kevin Reid-0/+13
This behavior is worth documenting because there are other plausible alternatives, such as panicking when a duplicate is encountered, and it reminds the programmer to consider whether they should, for example, coalesce duplicate keys first.

2024-11-18Improve `{BTreeMap,HashMap}::get_key_value` docs.Nicholas Nethercote-4/+36
They are unusual methods. The docs don't really describe the cases when they might be useful (as opposed to just `get`), and the examples don't demonstrate the interesting cases at all. This commit improves the docs and the examples.

2024-04-17Rollup merge of #122201 - coolreader18:doc-clone_from, r=dtolnayMatthias Krüger-2/+6
Document overrides of `clone_from()` in core/std As mentioned in https://github.com/rust-lang/rust/pull/96979#discussion_r1379502413 Specifically, when an override doesn't just forward to an inner type, document the behavior and that it's preferred over simply assigning a clone of source. Also, change instances where the second parameter is "other" to "source". I reused some of the wording over and over for similar impls, but I'm not sure that the wording is actually *good*. Would appreciate feedback about that. Also, now some of these seem to provide pretty specific guarantees about behavior (e.g. will reuse the exact same allocation iff the len is the same), but I was basing it off of the docs for [`Box::clone_from`](https://doc.rust-lang.org/1.75.0/std/boxed/struct.Box.html#method.clone_from-1) - I'm not sure if providing those strong guarantees is actually good or not.

2024-02-22Add `rustc_confusables` annotations to some stdlib APIsEsteban Küber-0/+5
Help with common API confusion, like asking for `push` when the data structure really has `append`. ``` error[E0599]: no method named `size` found for struct `Vec<{integer}>` in the current scope --> $DIR/rustc_confusables_std_cases.rs:17:7 | LL | x.size(); | ^^^^ | help: you might have meant to use `len` | LL | x.len(); | ~~~ help: there is a method with a similar name | LL | x.resize(); | ~~~~~~ ``` #59450

2023-06-15Auto merge of #104455 - the8472:dont-drain-on-drop, r=Amanieubors-73/+76
Don't drain-on-drop in DrainFilter impls of various collections. This removes drain-on-drop behavior from various unstable DrainFilter impls (not yet for HashSet/Map) because that behavior [is problematic](https://github.com/rust-lang/rust/issues/43244#issuecomment-641638196) (because it can lead to panic-in-drop when user closures panic) and may become forbidden if [this draft RFC passes](https://github.com/rust-lang/rfcs/pull/3288). closes #101122 [ACP](https://github.com/rust-lang/libs-team/issues/136) affected tracking issues * #43244 * #70530 * #59618 Related hashbrown update: https://github.com/rust-lang/hashbrown/pull/374
2023-06-14Rollup merge of #107619 - stepancheg:hash-set-insert, r=AmanieuMatthias Krüger-1/+23
