Error code E0747

Generic arguments were not provided in the same order as the corresponding generic parameters are declared.

Erroneous code example:

#![allow(unused)] fn main() { struct S<'a, T>(&'a T); type X = S<(), 'static>; // error: the type argument is provided before the // lifetime argument }

The argument order should be changed to match the parameter declaration order, as in the following:

#![allow(unused)] fn main() { struct S<'a, T>(&'a T); type X = S<'static, ()>; // ok }
