Struct CandidateIdentity 

pub struct CandidateIdentity {
    pub generation: u64,
    pub index: usize,
}

What: The identity of one candidate within one invocation. u64 is an unsigned 64-bit counter (siblings u32, usize); usize is the unsigned integer every index uses. Why: Identity must not be derived from the pathname, which the scanner may mask. The generation tells a candidate of an invalidated version from a current one; u64 cannot run out within a process. The index is the candidate’s position in its version, and usize is what indexing and the scanner take.

In TS you’d write (pseudocode):

type CandidateIdentity = { generation: bigint; index: number };

Fields

generation: u64

Counts invalidations: candidates of an earlier generation are stale.

index: usize

Zero-based position in the version’s candidate list.
