Add `#[track_caller]` to allocating methods of `Vec` & `VecDeque` Part 4 in a lengthy saga. r? `@joshtriplett` because they were the reviewer the last 3 times. `@bors` rollup=never "[just in case this has perf effects, Vec is hot](https://github.com/rust-lang/rust/pull/79323#issuecomment-731866746)" This was first attempted in #79323 by `@nvzqz.` It got approval from `@joshtriplett,` but rotted with merge conflicts and got closed. Then it got picked up by `@Dylan-DPC-zz` in #83359. A benchmark was run[^perf], the results (after a bit of thinking[^thinking]) were deemed ok[^ok], but there was a typo[^typo] and the PR was made from a wrong remote in the first place[^remote], so #83909 was opened instead. By the time #83909 rolled around, the methods in question had received some optimizations[^optimizations], so another perf run was conducted[^perf2]. The results were ok[^ok2]. There was a suggestion to add regression tests for panic behavior [^tests], but before it could be addressed, the PR fell victim to merge conflicts[^conflicts] and died again[^rip]. 3 years have passed, and (from what I can tell) this has not been tried again, so here I am now, reviving this old effort. Given how much time has passed and the fact that I've also touched `VecDeque` this time, it probably makes sense to `@bors` try `@rust-timer` [^perf]: https://github.com/rust-lang/rust/pull/83359#issuecomment-804450095 [^thinking]: https://github.com/rust-lang/rust/pull/83359#issuecomment-805286704 [^ok]: https://github.com/rust-lang/rust/pull/83359#issuecomment-812739031 [^typo]: https://github.com/rust-lang/rust/pull/83359#issuecomment-812750205 [^remote]: https://github.com/rust-lang/rust/pull/83359#issuecomment-814067119 [^optimizations]: https://github.com/rust-lang/rust/pull/83909#issuecomment-813736593 [^perf2]: https://github.com/rust-lang/rust/pull/83909#issuecomment-813825552 [^ok2]: https://github.com/rust-lang/rust/pull/83909#issuecomment-813831341 [^tests]: https://github.com/rust-lang/rust/pull/83909#issuecomment-825788964 [^conflicts]: https://github.com/rust-lang/rust/pull/83909#issuecomment-851173480 [^rip]: https://github.com/rust-lang/rust/pull/83909#issuecomment-873569771 |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
