What is the difference between <Type>::method() AND Type::method()?

Question

In Rust, is there difference between <Type>::method() and Type::method()? Any easy way to see the differences?

For example, this rocket swagger code uses <String>::responses(...).

Answer 1

They mean the same thing. However, Type::method() can only be used when Type is also a path. Other types may require using < > like:

• <[u8]>::method()
• <&str>::method()
• <(u8, u8)>::method()
• <Vec<u8>>::method() (though Vec::<u8>::method() does work too)
