Struct uuid::v1::Context

pub struct Context { /* fields omitted */ }

A thread-safe, stateful context for the v1 generator to help ensure process-wide uniqueness.

Methods

impl Context

pub fn new(count: u16) -> Self

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.

Trait Implementations

impl ClockSequence for Context

fn generate_sequence(&self, _: u64, _: u32) -> u16

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.

impl Debug for Context

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
