key-value operation.
Implementations§
source§impl<'a, K, V> Builder<'a, K, V>where
K: KeyValue,
V: Serialize + Send + Sync,
impl<'a, K, V> Builder<'a, K, V>where K: KeyValue, V: Serialize + Send + Sync,
sourcepub fn expire_in(self, duration: Duration) -> Self
pub fn expire_in(self, duration: Duration) -> Self
Set this key to expire after duration
from now.
sourcepub fn expire_at(self, time: SystemTime) -> Self
pub fn expire_at(self, time: SystemTime) -> Self
Set this key to expire at the provided time
.
sourcepub const fn keep_existing_expiration(self) -> Self
pub const fn keep_existing_expiration(self) -> Self
If the key already exists, do not update the currently set expiration.
sourcepub const fn only_if_exists(self) -> Self
pub const fn only_if_exists(self) -> Self
Only set the value if this key already exists.
sourcepub const fn only_if_vacant(self) -> Self
pub const fn only_if_vacant(self) -> Self
Only set the value if this key isn’t present.
sourcepub fn returning_previous(self) -> Result<Option<Value>, Error>
pub fn returning_previous(self) -> Result<Option<Value>, Error>
Executes the Set operation, requesting the previous value be returned. If no change is made, None will be returned.
sourcepub fn returning_previous_as<OtherV: for<'de> Deserialize<'de>>(
self
) -> Result<Option<OtherV>, Error>
pub fn returning_previous_as<OtherV: for<'de> Deserialize<'de>>( self ) -> Result<Option<OtherV>, Error>
Executes the Set operation, requesting the previous value be returned. If no change is made, None will be returned.
