Struct MemoryStore 

pub struct MemoryStore<S>(/* private fields */);

State held in this process and nowhere else: no disk, and no visibility to a second process.

Implementations

impl<S> MemoryStore<S>

pub fn new(state: S) -> Self

Hold this state in memory.

Trait Implementations

impl<S> Clone for MemoryStore<S>

A second handle on the same state, which is what lets a host factory hand out a per-repository host that a journey can still read back through the value it created.

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for MemoryStore<S>

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

Formats the value using the given formatter.

impl<S: Clone> Store<S> for MemoryStore<S>

fn with<R, F>(&self, act: F) -> Result<R>

where F: FnOnce(&mut S) -> Result<R>,

Read the state, act on it, and keep whatever the action left.

fn snapshot(&self) -> Result<S>

The state as it stands.
