详细描述

Injectable UUIDv7 generator.

UUIDv7 contains a Unix-millisecond timestamp and random bits. This class assembles the value but does not provide entropy itself. The caller owns the security and availability properties of the injected entropy source.

构造及析构函数说明

UuidV7Generator()

eve::UuidV7Generator::UuidV7Generator ( UuidEntropySource  entropy, UuidClock  clock = {}  )

explicit

Creates a generator with an injected entropy source and optional clock.

参数

entropy	Source for the UUID random portion; an empty source makes generation fail.
clock	Source for the timestamp; an empty source uses system_clock at call time.
