Enum rustix::time::DynamicClockId

#[non_exhaustive]
pub enum DynamicClockId<'a> {
    Known(ClockId),
    Dynamic(BorrowedFd<'a>),
    RealtimeAlarm,
    Tai,
    Boottime,
    BoottimeAlarm,
}

CLOCK_* constants for use with clock_gettime_dynamic.

These constants may be unsupported at runtime, depending on the OS version, and clock_gettime_dynamic may fail with INVAL. See ClockId for clocks which are always supported at runtime.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Known(ClockId)

ClockId values that are always supported at runtime.

Dynamic(BorrowedFd<'a>)

Linux dynamic clocks.

RealtimeAlarm

CLOCK_REALTIME_ALARM, available on Linux >= 3.0

Tai

CLOCK_TAI, available on Linux >= 3.10

Boottime

CLOCK_BOOTTIME, available on Linux >= 2.6.39

BoottimeAlarm

CLOCK_BOOTTIME_ALARM, available on Linux >= 2.6.39
