Regarding different pointer types in Rust as function

A function that takes a borrowed pointer &T can also be called

to a &T. One function to rule them ... err .. accomodate all.
Again, what happens with:
T identity(T t) { return t; }
? I.e. the transference of the argument pointer type to the
return type?
The compiler already infers @safe nothrow pure on template
functions. Couldn't it do the same for @nullable?
