Struct CheckpointFuture

Source

pub struct CheckpointFuture { /* private fields */ }

Expand description

Result of an asynchronous checkpoint operation.

The checkpoint is being written in a background thread. Call wait to block until completion and retrieve any error.

Implementations§

Source §

impl CheckpointFuture

Source

pub fn wait(&mut self) -> Result<(), DistCheckpointError>

Block until the checkpoint write completes.

Returns Ok(()) if the write succeeded, or the error encountered during serialization/I/O.

Calling wait() multiple times is safe — subsequent calls return the cached result.

Source

pub fn is_done(&self) -> bool

Returns true if the background write has completed (success or failure).
