Use `fn` ptr signature instead of `{closure@..}` in infer error
When suggesting a type on inference error, do not use `{closure@..}`. Instead, replace with an appropriate `fn` ptr.
On the error message, use `short_ty_string` and write long types to disk.

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).
