Enum Resolved 

pub enum Resolved<T> {
    Exact(T),
    Ambiguous(Vec<T>),
    Unresolved(String),
}

The outcome of any lookup the analyzer performs.

Generic on purpose: every resolution step (field type, callee, prefix) returns one of these, so “we did not know” is representable everywhere and cannot decay into a default.

Variants

Exact(T)

Exactly one answer, statically certain.

Ambiguous(Vec<T>)

Several possible answers and no way to choose. Never silently pick the first.

Unresolved(String)

Nothing could be determined. Carries why, for the diagnostic stream.
