Enum rustix::time::DynamicClockId

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

clockid_t 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)§

This enum is marked as 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

§

Tai

CLOCK_TAI, available on Linux ≥ 3.10

§

Boottime

CLOCK_BOOTTIME

§

BoottimeAlarm

CLOCK_BOOTTIME_ALARM
