Struct BufferedSessionMetadataStore 

pub struct BufferedSessionMetadataStore { /* private fields */ }

Background writer for runtime session metadata snapshots.

Each queued snapshot is written in order, and every write replaces the previous file atomically. The handle itself only performs channel sends; filesystem work happens on its worker thread. flush is the explicit durability boundary used before a session exits.

Implementations

impl BufferedSessionMetadataStore

pub fn write(&self, metadata: SessionMetadata) -> Result<(), PersistenceError>

Queue a complete metadata snapshot without doing filesystem I/O in the caller.

pub fn flush(&self) -> Result<(), PersistenceError>

Drain queued snapshots and wait until the latest one is durable.

Trait Implementations

impl Debug for BufferedSessionMetadataStore

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

Formats the value using the given formatter.

impl Drop for BufferedSessionMetadataStore

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
