Enum Specificity 

pub enum Specificity {
    ProductAndVersion,
    ProductOnly,
    ProtocolOnly,
    Weak,
}

The confidence ladder. Every rule declares which rung it sits on, so scores across protocols mean the same thing and are auditable in one table rather than sprinkled as magic numbers through match arms (AC-4.11).

Variants

ProductAndVersion

Product and version both extracted from a self-identifying banner.

ProductOnly

Product identified, version absent or unparseable.

ProtocolOnly

Protocol confirmed by structure, product unknown.

Weak

Consistent with the service but not conclusive.

Implementations

impl Specificity

pub const ALL: [Self; 4]

Every rung, in ladder order.

Exists so the exhaustiveness of the ladder is testable rather than eyeballed: tests::every_rung_of_the_ladder_is_a_valid_confidence walks this array, and tests::the_ladder_array_lists_every_variant matches on each variant exhaustively, so adding a fifth rung without adding it here fails to compile.

pub fn confidence(self) -> Confidence
