Struct Shared 

pub struct Shared<S> { /* private fields */ }

A cloneable, shareable handle to a store.

Reader/Writer take &mut self, so sharing a store between owners requires a lock. Shared is that lock, packaged: it implements the store traits over Arc<Mutex<S>> so callers don’t hand-roll the wrapper. Lock poisoning is recovered from (the store may be mid-update, but path-level operations are individually atomic).

Implementations

impl<S> Shared<S>

pub fn new(inner: S) -> Self

Wrap a store for shared access.

pub fn lock(&self) -> MutexGuard<'_, S>

Access the underlying store directly.

Trait Implementations

impl<S> Clone for Shared<S>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Reader> Reader for Shared<S>

fn read(&mut self, from: &Path) -> Result<Option<Record>, Error>

Read a record from a path.

fn read_children(&mut self, from: &Path) -> Result<Option<Vec<String>>, Error>

Enumerate the child names directly under a path.

impl<S: Writer> Writer for Shared<S>

fn write(&mut self, to: &Path, data: Record) -> Result<Path, Error>

Write a record to a path.
