An inherent implementation was defined for a type outside the current crate.
Erroneous code example:
impl Vec<u8> { } // error
RunYou can only define an inherent implementation for a type in the same crate
where the type was defined. For example, an impl
block as above is not allowed
since Vec
is defined in the standard library.
To fix this problem, you can either:
Note that using the type
keyword does not work here because type
only
introduces a type alias:
type Bytes = Vec<u8>;
impl Bytes { } // error, same as above
