Struct InMemoryBackend 

pub struct InMemoryBackend { /* private fields */ }

Ephemeral in-process session: nothing persisted to disk.

Override the granular methods to skip the clone overhead of the full snapshot path (we’re already in memory, so direct field mutations are cheaper than clone→mutate→replace).

Implementations

impl InMemoryBackend

pub fn new() -> Self

pub fn snapshot(&self) -> Option<PersistedSession>

Test helper: get a snapshot of the current in-memory state.

Trait Implementations

impl Default for InMemoryBackend

fn default() -> InMemoryBackend

Returns the “default value” for a type.

fn delete(&self) -> Result<()>

fn name(&self) -> &str
