Such impl does not exist, and probably never will, but the rules are the same among all types, and in the general case this definitely can happen. The reason for these rules is that nothing prevents Range or Vec from implementing impl Index> for Vec. Type aliases do not affect locality.Īs neither Index nor Range nor Vec are local, and Range is not a fundamental type, you cannot impl Index> for Vec, no matter what you put in the place of the. struct Foo is considered local, but Vec is not. This is not affected by applied type arguments. Given trait Foo, Foo is always local, regardless of the types substituted for T and U.Ī struct, enum, or union which was defined in the current crate. A trait definition is local or not independent of applied type arguments. The T in Box is not considered covered, and Box is considered local.Ī trait which was defined in the current crate. Note that for the purposes of coherence, fundamental types are special. Only the appearance of uncovered type parameters is restricted.
