Add `size_of` and `size_of_val` and `align_of` and `align_of_val` to the prelude (Note: need to update the PR to add `align_of` and `align_of_val`, and remove the second commit with the myriad changes to appease the lint.) Many, many projects use `size_of` to get the size of a type. However, it's also often equally easy to hardcode a size (e.g. `8` instead of `size_of::<u64>()`). Minimizing friction in the use of `size_of` helps ensure that people use it and make code more self-documenting. The name `size_of` is unambiguous: the name alone, without any prefix or path, is self-explanatory and unmistakeable for any other functionality. Adding it to the prelude cannot produce any name conflicts, as any local definition will silently shadow the one from the prelude. Thus, we don't need to wait for a new edition prelude to add it. |

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).
