HEXPIRE

The key of the hash.

The field or fields to set an expiration time for.

The time-to-live (TTL) in seconds.

Optional condition for setting the expiration:

• NX: Set the expiration only if the field does not already have an expiration.
• XX: Set the expiration only if the field already has an expiration.
• GT: Set the expiration only if the new TTL is greater than the current TTL.
• LT: Set the expiration only if the new TTL is less than the current TTL.

A list of integers indicating whether the expiry was successfully set.

• -2 if the field does not exist in the hash or if key doesn't exist.
• 0 if the expiration was not set due to the condition.
• 1 if the expiration was successfully set.
• 2 if called with 0 seconds/milliseconds or a past Unix time.
