Expand description

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)
