Variants§
Found(T)
Data was found
Deleted(BlobRecordTimestamp)
Data was deleted, contains creation timestamp
NotFound
Data was not found
Implementations§
source§impl<T> ReadResult<T>
impl<T> ReadResult<T>
sourcepub fn is_deleted(&self) -> bool
pub fn is_deleted(&self) -> bool
Is this deleted result
sourcepub fn is_not_found(&self) -> bool
pub fn is_not_found(&self) -> bool
Is this not found result
sourcepub fn into_option(self) -> Option<T>
pub fn into_option(self) -> Option<T>
Convert to option if data exists
sourcepub fn map<Y>(self, f: impl FnOnce(T) -> Y) -> ReadResult<Y>
pub fn map<Y>(self, f: impl FnOnce(T) -> Y) -> ReadResult<Y>
Map data if it exists
sourcepub fn cast<Y>(self) -> ReadResult<Y>
pub fn cast<Y>(self) -> ReadResult<Y>
Cast result to type only if does not contain value Warning: panics if result contains value
sourcepub async fn map_async<Y, F>(self, f: impl FnOnce(T) -> F) -> ReadResult<Y>where
F: Future<Output = Y>,
pub async fn map_async<Y, F>(self, f: impl FnOnce(T) -> F) -> ReadResult<Y>where
F: Future<Output = Y>,
Map data if it exists
source§impl ReadResult<BlobRecordTimestamp>
impl ReadResult<BlobRecordTimestamp>
sourcepub fn latest(
self,
other: ReadResult<BlobRecordTimestamp>
) -> ReadResult<BlobRecordTimestamp>
pub fn latest( self, other: ReadResult<BlobRecordTimestamp> ) -> ReadResult<BlobRecordTimestamp>
Returns ReadResult<BlobRecordTimestamp>
with max timetamp.
If timestamps are equal, then self
is preserved
source§impl ReadResult<Entry>
impl ReadResult<Entry>
sourcepub fn latest(self, other: ReadResult<Entry>) -> ReadResult<Entry>
pub fn latest(self, other: ReadResult<Entry>) -> ReadResult<Entry>
Returns ReadResult<Entry>
with max timetamp.
If timestamps are equal, then self
is preserved
