This allows it to sort of "lock in" which procedure will be called, which improves performance, allows for compile time evaluation, and dead code elimination. WebRust must use dynamic dispatch for the Iterator's methods (because Rust does not know where, at compile time, the memory location of the methods are). Rust cannot accept ownership of an object that implements the Iterator trait in this manner (because passing it in parameters like this would require Rust to know the size of the object so it ...
