Enum rustix::time::DynamicClockId

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
