Enum StampKind 

#[repr(u32)]
pub enum StampKind {
    Tsc = 0,
    SharedCounter = 1,
    Monotonic = 2,
}

Which clock the stamps come from. Fixed at region creation; openers read it from the header so every process attached to the ring stamps from the same source.

Variants

Tsc = 0

rdtsc behind the invariant-TSC probe.

SharedCounter = 1

fetch_add on the header’s shared_stamp atom.

Monotonic = 2

System-wide monotonic clock in nanoseconds.

Implementations

impl StampKind

pub fn has_time_semantics(self) -> bool

Whether stamps carry time semantics (enables the freshness guard in MergeByStamp).

pub fn freshness_guard(self) -> Option<u64>

The freshness-guard window for this stamp kind, in the stamp unit. None for counter stamps (no time semantics; exactness comes from MergeStrict’s watermark gate instead).
