Enum pearl::ReadResult

pub enum ReadResult<T> {
    Found(T),
    Deleted(BlobRecordTimestamp),
    NotFound,
}

Result of read operations

Variants

Found(T)

Data was found

Deleted(BlobRecordTimestamp)

Data was deleted, contains creation timestamp

NotFound

Data was not found

Implementations

impl<T> ReadResult<T>

pub fn is_found(&self) -> bool

Is this found result

pub fn is_deleted(&self) -> bool

Is this deleted result

pub fn is_not_found(&self) -> bool

Is this not found result

pub fn into_option(self) -> Option<T>

Convert to option if data exists

pub fn map<Y>(self, f: impl FnOnce(T) -> Y) -> ReadResult<Y>

Map data if it exists

pub fn cast<Y>(self) -> ReadResult<Y>

Cast result to type only if does not contain value Warning: panics if result contains value

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

pub fn unwrap(self) -> T

Unwrap into data, panics if no data is set

impl 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

impl 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

Trait Implementations

impl<T: Debug> Debug for ReadResult<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq<ReadResult<T>> for ReadResult<T>

fn eq(&self, other: &ReadResult<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
