pub struct UuidV1Context { /* fields omitted */ }
A thread-safe, stateful context for the v1 generator to help
ensure process-wide uniqueness.
Creates a thread-safe, internally mutable context to help
ensure uniqueness.
This is a context which can be shared across threads. It
maintains an internal counter that is incremented at every
request, the value ends up in the clock_seq portion of the
Uuid (the fourth group). This will improve the probability
that the Uuid is unique across the process.
Return a 16-bit number that will be used as the "clock sequence" in the Uuid. The number must be different if the time has changed since the last time a clock sequence was requested. Read more
