Enum DatabaseTimeToLive

pub enum DatabaseTimeToLive {
    Forever,
    Duration(Duration),
}

Time To Live for database, which can be Forever, or a Duration, but can’t be Instant.

unlike TimeToLive which can be Instant, Forever, or a Duration

Variants

Forever

Keep the data forever

Duration(Duration)

Duration to keep the data, this duration should be non-zero

Implementations

impl DatabaseTimeToLive

pub fn from_humantime_or_str(s: &str) -> Result<Self, Error>

Parse a string that is either forever, or a duration to TimeToLive

note that an empty string or a zero duration(a duration that spans no time) is treat as forever too
