Expand description
clockid_t
CLOCK_*
constants for use with clock_gettime
.
These constants are always supported at runtime, so clock_gettime
never
has to fail with INVAL
due to an unsupported clock. See
DynamicClockId
for a greater set of clocks, with the caveat that not
all of them are always supported.
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.
Realtime = 0
CLOCK_REALTIME
Monotonic = 1

On FreeBSD, use Self::Uptime
, as CLOCK_BOOTTIME
is an alias for
CLOCK_UPTIME
.
