Struct EntryTierIdentity 

pub struct EntryTierIdentity {
    pub engine: u64,
    pub scope: EntryScope,
    pub type_rules_fingerprint: u64,
    pub reducers_fingerprint: u64,
}

Identity of an entry tier: the entries a store holds and the roll-ups derived from them.

.gitignore observation is deliberately not part of it. Reading control files changes which entries are classified as ignored, never which entries exist or what they measure, so a store taken with observation on and one taken with it off hold equal entry tiers. That is what lets a later projection serve one from the other.

Fields

engine: u64

The engine fingerprint of the build that produced the tier (crate::snapshot::engine_fingerprint).

scope: EntryScope

Which entries a scan retains.

type_rules_fingerprint: u64

Identity of the type-classification rules roll-ups were tallied under.

reducers_fingerprint: u64

Identity of the enabled reducer set.
