Enum ResolutionGap 

pub enum ResolutionGap {
    ExternalDefinition,
    DynamicDispatch,
    MacroExpansion,
    MissingDefinition,
    UnsupportedSyntax,
    ConditionalCompilation,
    Ambiguous,
}

Why a reference did not resolve, or resolved only to possibilities.

Filesystem closure failures are errors before a report exists, so they are not gaps.

Variants

ExternalDefinition

The target is outside the indexed corpus.

DynamicDispatch

The target is chosen at run time.

MacroExpansion

The target would come from an expansion this tier does not perform.

MissingDefinition

The corpus contains no matching definition.

UnsupportedSyntax

The reference form is not one this tier resolves.

ConditionalCompilation

Conditional compilation leaves the active universe unknown.

Ambiguous

More than one definition matches and none is provably the target.
