Enum Backoff 

pub enum Backoff {
    Spin,
    Yield,
    Sleep,
}

Available on crate features ulid and thread-local only.

Backoff strategies for handling monotonic ULID overflow.

If multiple ULIDs are generated in the same millisecond and the random component is exhausted, the generator invokes one of these strategies to wait before retrying.

Variants

Spin

Busy-waits in a tight loop.

Offers maximum throughput at the cost of high CPU usage.

Yield

Yields to the OS scheduler to allow other threads to run.

More CPU-friendly than spinning, but may still busy-wait if no other threads are ready.

Sleep

Sleeps for the requested retry delay in milliseconds.

Lowest CPU usage, but may oversleep depending on platform-specific scheduler resolution.
