Struct DerivedContextGap 

pub struct DerivedContextGap {
    pub class: Name,
    pub missing: String,
    pub part: DerivedPart,
    pub argument: String,
}

A constraint a derived instance needs and the context written on it does not provide — see Error::DerivedInstanceContextTooNarrow.

part: DerivedPart

The first argument that needs it was found in this.

argument: String
