- Successful merges: Provide hint when cast needs a dereference #37442, Type walker small vector #37760, Clarify the reference's status. #37836, Add a regression test for issue 23699. #37851, Add missing examples for Ipv6Addr #37859, Add missing examples for SocketAddrV4 #37913, Add some internal docs links for Args/ArgsOs #37925
- Failed merges:
The former wording only gave part of the picture, we want to be crystal clear about this.
For a given code: ```rust vec![0.0].iter().map(|s| s as i16).collect::<Vec<i16>>(); ``` display: ```nocode error: casting `&f64` as `i16` is invalid --> foo.rs:2:35 | 2 | vec![0.0].iter().map(|s| s as i16).collect::<Vec<i16>>(); | - ^^^ cannot cast `&f64` as `i16` | | | did you mean `*s`? ``` instead of: ```nocode error: casting `&f64` as `i16` is invalid --> <anon>:2:30 | 2 | vec![0.0].iter().map(|s| s as i16).collect(); | ^^^^^^^^ | = help: cast through a raw pointer first ```
The change also adds the missing `SmallVec::truncate` method.

… r=arielb1 Type walker small vector These two changes avoid allocations on some hot paths and speed up a few workloads (some from rustc-benchmarks, as well as the workload from rust-lang#36799) by 1--2%.
…ence-comment, r=GuillaumeGomez Clarify the reference's status. The former wording only gave part of the picture, we want to be crystal clear about this. /cc @petrochenkov, who had concerns about rust-lang#37820
Add a regression test for issue 23699. This should close rust-lang#23699
Add missing examples for SocketAddrV4 r? @steveklabnik cc @frewsxcv
…eklabnik Add some internal docs links for Args/ArgsOs In many places the docs link to other sections and I noticed it was lacking here. Not sure if there is a standard for if inter-linking is appropriate.
…es, r=eddyb Move the myriad-closures.rs test case to run-pass-full test suite. r? @eddyb
