In gfx examples they type a parameter using &mut <back::Backend as hal::Backend>::Surface
. Is &mut back::Backend::Surface
equivalent or any difference?

<Type as Trait>
is used to specify that you're specifically referring to the members of Trait
as implemented for Type
. Normally, the compiler works this out itself. You need to write this out when the compiler complains that it doesn't know what you're talking about because it got confused somewhere.
