Difference between `my_func` vs `my_func where T: MyTrait`

Question

Whats the difference between

my_func<T: MyTrait>(...) {...}

and

my_func<T>(...) where T: MyTrait {...}

?

Answer 1

One is written with an explicit where clause, the other isn't.

Okay, okay; if you want to be picky, the differences are:

• You can't introduce a generic parameter with a where clause.
• You can't constrain anything other than generic parameters in the generic argument list.

But in terms of what changes when you move constraints from the generic argument list to a where clause, they're the same.
