An inherent implementation was defined for something which isn't a struct nor an enum.
Erroneous code example:
impl (u8, u8) { // error: no base type found for inherent implementation fn get_state(&self) -> String { // ... } }
To fix this error, please implement a trait on the type or wrap it in a struct. Example:
// we create a trait here trait LiveLongAndProsper { fn get_state(&self) -> String; } // and now you can implement it on (u8, u8) impl LiveLongAndProsper for (u8, u8) { fn get_state(&self) -> String { "He's dead, Jim!".to_owned() } }
Alternatively, you can create a newtype. A newtype is a wrapping tuple-struct. For example, NewType
is a newtype over Foo
in struct NewType(Foo)
. Example:
struct TypeWrapper((u8, u8)); impl TypeWrapper { fn get_state(&self) -> String { "Fascinating!".to_owned() } }
