Hlc<T> class Null safety

A Hybrid Logical Clock implementation. This class trades time precision for a guaranteed monotonically increasing clock in distributed systems. Inspiration: https://cse.buffalo.edu/tech-reports/2014-04.pdf

Implemented types

Constructors

Hlc(int millis, int counter, T nodeId)
Hlc.fromDate(DateTime dateTime, T nodeId)
Hlc.fromLogicalTime(dynamic logicalTime, T nodeId)
Hlc.now(T nodeId)
Hlc.parse(String timestamp, [T idDecoder(String value)?])
factory
Hlc.recv(Hlc<T> canonical, Hlc<T> remote, {int? millis})
Compares and validates a timestamp from a remote system with the local canonical timestamp to preserve monotonicity. Returns an updated canonical timestamp instance. Local wall time will be used if millis isn't supplied.
factory
Hlc.send(Hlc<T> canonical, {int? millis})
Generates a unique, monotonic timestamp suitable for transmission to another system in string format. Local wall time will be used if millis isn't supplied.
factory
Hlc.zero(T nodeId)
