Struct DeterministicClockGuard 

pub struct DeterministicClockGuard { /* private fields */ }

RAII guard: sets the deterministic epoch on construction and restores the wall clock on drop. Hold it for the lifetime of a generation run.

Implementations

impl DeterministicClockGuard

pub fn new(epoch: DateTime<Utc>) -> Self

Activate the deterministic clock at epoch (timestamps only; the UUID fallback is left untouched).

pub fn from_seed(seed: u64, start_date: NaiveDate) -> Self

Activate the full deterministic context — clock epoch + seeded UUID fallback — for a generation run keyed off seed/start_date.

Trait Implementations

impl Drop for DeterministicClockGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
