Enum FrameResolution 

pub enum FrameResolution {
    Resolved,
    Ambiguous,
    NotFound,
    NotAttempted,
}

What the project graph could say about a frame’s identifier.

not_attempted is not a softer not_found: it records that the graph was never consulted, because the frame does not point at project source. Keeping them apart is what lets resolved + ambiguous + not_found + not_attempted equal the frame count without any of the four lying about what it measured.

Variants

Resolved

Exactly one definition matched. candidates holds that one entry.

Ambiguous

More than one definition matched. Every match is listed and none is preferred; the caller decides, or narrows the question.

NotFound

The graph was asked and knows no definition under this identifier. A module-local function is not in the graph’s definition set, so this is also the answer for a frame naming one.

NotAttempted

The graph was not asked. Either the frame does not point at project source, or it points at project source but carries nothing addressable to ask about: no printed function name, or a placeholder such as Object.<anonymous>. reason names which case applies, so this is never a silent shrug.
