Enum rustix::time::ClockId

source ·
#[non_exhaustive]
#[repr(i32)]
pub enum ClockId { Realtime = 0, Monotonic = 1, ProcessCPUTime = 2, ThreadCPUTime = 3, RealtimeCoarse = 5, MonotonicCoarse = 6, MonotonicRaw = 4, RealtimeAlarm = 8, Boottime = 7, BoottimeAlarm = 9, }
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

CLOCK_MONOTONIC

ProcessCPUTime = 2

CLOCK_PROCESS_CPUTIME_ID

RealtimeAlarm = 8

CLOCK_REALTIME_ALARM

Boottime = 7

CLOCK_BOOTTIME

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