Struct Snapshot 

pub struct Snapshot<T> { /* private fields */ }

A stable, zero-copy view of the data currently retained by an AtomicLog.

A snapshot owns Arcs to every segment it exposes, so the underlying storage remains alive for the lifetime of the snapshot. Refreshing a snapshot replaces its contents with a newer captured view.

Implementations

impl<T> Snapshot<T>

pub fn refresh(&mut self)

Refreshes the snapshot in place to reflect the current state of the log.

This attempts a cheap same-head extension first, then an incremental segment append, and falls back to a full rebuild if continuity has been lost.

pub fn len(&self) -> usize

Returns the total number of elements visible through this snapshot.

pub fn is_empty(&self) -> bool

Returns true if the snapshot contains no elements.

pub fn iter(&self) -> Iter<'_, T>

Iterates over all visible values as a flat &T stream.

pub fn chunks(&self) -> Chunks<'_, T>

Iterates over the snapshot one backing segment at a time.

pub fn log(&self) -> AtomicLog<T>

Returns a read handle for the log this snapshot came from.

Trait Implementations

impl<T> Debug for Snapshot<T>

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

Formats the value using the given formatter.

impl<T> From<AtomicLog<T>> for Snapshot<T>

fn from(log: AtomicLog<T>) -> Self

Converts to this type from the input type.

impl<T> From<Snapshot<T>> for AtomicLog<T>

fn from(snapshot: Snapshot<T>) -> Self

Converts to this type from the input type.

impl<'a, T> IntoIterator for &'a Snapshot<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
