Quote of the Week
There actually are NOT very many places where the C code’s behavior conflicts with Rust’s borrowing rules. This is both somewhat surprising, because there’s no way this code was written with Rust’s borrowing semantics in mind, and also entirely sensible, since Rust’s borrowing semantics are often quite close to how you actually want your code to behave anyway.
– SimonHeath porting C to Rust
Thanks to StyMaar for the suggestion!
