Enum Expiration 

pub enum Expiration {
    Never,
    Seconds(u32),
    Unix(u32),
}

Expiration policy for a stored item.

memcached interprets the on-wire expiry field as follows: 0 means never expire; a value up to 60 * 60 * 24 * 30 (30 days) is a relative number of seconds; any larger value is an absolute unix timestamp.

Variants

Never

Never expire (wire value 0).

Seconds(u32)

Expire after this many seconds from now.

Unix(u32)

Expire at this absolute unix timestamp (seconds).

Implementations

impl Expiration

pub fn to_wire(self) -> u32

The raw value written to the protocol’s expiry field.

Trait Implementations

impl Clone for Expiration

fn clone(&self) -> Expiration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Expiration

impl Debug for Expiration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Expiration

fn default() -> Expiration

Returns the “default value” for a type.

impl Eq for Expiration

impl From<Duration> for Expiration

fn from(duration: Duration) -> Self

Converts to this type from the input type.

impl From<Option<Duration>> for Expiration

fn from(duration: Option<Duration>) -> Self

Converts to this type from the input type.

impl From<u32> for Expiration

fn from(secs: u32) -> Self

A number of seconds. 0 maps to Expiration::Never; values greater than 30 days are passed through unchanged (treated as unix timestamps by the server).

impl PartialEq for Expiration

fn eq(&self, other: &Expiration) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
