Struct ItemFingerprint 

pub struct ItemFingerprint {
    pub parts: Vec<PartDigest>,
}

What an item contained when a run measured it.

A report carries one per item so a later comparison can ask is this still the same experiment? An ItemFingerprint with no parts is “unknown” — it comes from a report written before fingerprints existed — and a comparison says so rather than pretending the pairing was checked.

Fields

parts: Vec<PartDigest>

One digest per part, in ItemPart::ALL order.

Implementations

impl ItemFingerprint

pub fn is_unknown(&self) -> bool

Returns true when nothing was recorded, so no pairing can be checked.

pub fn digest_of(&self, part: ItemPart) -> Option<&str>

The digest recorded for part.

pub fn provenance_of(&self, part: ItemPart) -> PartProvenance

Where the corpus said part came from.

PartProvenance::Authored for a part nothing was recorded about, which is the conservative reading: an authored part that moved breaks a pairing, so an absent declaration never quietly excuses a difference.

pub fn differing_parts(&self, other: &Self) -> Vec<ItemPart>

The parts both fingerprints recorded and disagree about.

Empty when either side is unknown: nothing can be concluded from a digest that was never taken.
