Struct QueueItem

pub struct QueueItem<'basedir, V: DeserializeOwned + Serialize + 'static> { /* private fields */ }

The self-referencing struct.

Implementations

impl<'basedir, V: DeserializeOwned + Serialize> QueueItem<'basedir, V>

pub fn from_entry<'s>( entry: Entry<'s, TimeKey, V>, base_dir: &PathBuf, opts: QueueGetItemOptions, ) -> Result<QueueItem<'s, V>, KeyValError>

pub fn key(&self) -> Result<TimeKey, KeyValError>

Get the key inside this queue, usable with get_entry (careful, there is no check against using it in the wrong queue!)

pub fn delete(&self) -> Result<(), KeyValError>

Delete this item now (alternatively, give delete_first in QueueIterationOptions)

pub fn lock_exclusive<'s>( &'s self, ) -> Result<ExclusiveFileLock<'s, File>, KeyValError>

Lock this item lazily (when no_lock == true given, but now a lock is needed). If no_lock was false, then this gives a KeyValError::AlreadyLocked error rather than dead-locking.

Trait Implementations

impl<'basedir, V: DeserializeOwned + Serialize + 'static + Debug> Debug for QueueItem<'basedir, V>

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

Formats the value using the given formatter.

impl<'basedir, V: DeserializeOwned + Serialize + 'static> Drop for QueueItem<'basedir, V>

fn drop(&mut self)

Executes the destructor for this type.

impl<'basedir, V: DeserializeOwned + Serialize + 'static + Debug> PartialEq for QueueItem<'basedir, V>

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

Tests for self and other values to be equal, and is used by ==.

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

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