Unrolled build for #147171
Rollup merge of #147171 - Qelxiros:hashmap_diag, r=fee1-dead

recommend using a HashMap if a HashSet's second generic parameter doesn't implement BuildHasher

closes rust-lang/rust#147147

~The suggestion span is wrong, but I'm not sure how to find the right one.~ fixed

I'm relatively new to the diagnostics ecosystem, so I'm not sure if `span_help` is the right choice. `span_suggestion_*` might be better, but the output from `x test` looks weird in that case.

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 integrated 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).
