Module time 

Compact monotonic time utilities.

Uses a process-local monotonic clock for timestamps that are smaller than std::time::Instant (8 bytes vs 16 bytes for Option).

All internal expiry values are stored as monotonic milliseconds since process start. Use monotonic_to_unix_ms to convert to wall-clock Unix timestamps for commands like EXPIRETIME and PEXPIRETIME.

Constants

NO_EXPIRY

Sentinel value meaning “no expiry”.

Functions

expiry_from_duration

Converts a Duration to an absolute expiry timestamp.

is_expired

Returns true if the given expiry timestamp has passed.

monotonic_to_unix_ms

Converts a monotonic expiry timestamp (ms since process start) to a Unix epoch timestamp in milliseconds.

now_ms

Returns current monotonic time in milliseconds since process start.

now_secs

Returns current monotonic time in seconds since process start, as u32.

remaining_ms

Returns remaining TTL in milliseconds, or None if no expiry.

remaining_secs

Returns remaining TTL in seconds, or None if no expiry.

unix_ms_to_monotonic_ms

Converts a Unix epoch timestamp in milliseconds to a monotonic expiry value suitable for storage in Entry::expires_at_ms.
