Struct RecordVersion 

pub struct RecordVersion { /* private fields */ }

Which record, and where in that record’s history, a write applies.

A sequence number alone identifies a position but not a record: a deregistered and re-registered URI starts counting again from zero, and a proof captured before the gap would sit above the new record’s history. The registration time pins the instance so it cannot.

Implementations

impl RecordVersion

pub const fn new(registered_at: SystemTime, sequence: u64) -> Self

Names a version explicitly, for a caller holding the parts rather than the record.

pub fn of(record: &Registration) -> Self

The version record currently holds.

pub fn next(record: &Registration) -> Self

The version the next write to record claims.

pub const fn registered_at(&self) -> SystemTime

Returns the registration time identifying the record instance.

pub const fn sequence(&self) -> u64

Returns the sequence number.
