Struct FileCheckpointStorage 

pub struct FileCheckpointStorage { /* private fields */ }

File-based checkpoint storage: one JSON file per checkpoint in a directory.

Implementations

impl FileCheckpointStorage

pub fn new(dir: impl Into<PathBuf>) -> Result<FileCheckpointStorage, Error>

Open (creating if necessary) file storage rooted at dir.

Trait Implementations

impl CheckpointStorage for FileCheckpointStorage

fn save<'life0, 'async_trait>( &'life0 self, checkpoint: WorkflowCheckpoint, ) -> Pin<Box<dyn Future<Output = Result<String, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, FileCheckpointStorage: 'async_trait,

Persist a checkpoint, returning its id.

fn load<'life0, 'life1, 'async_trait>( &'life0 self, checkpoint_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<WorkflowCheckpoint>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, FileCheckpointStorage: 'async_trait,

Load a checkpoint by id, or None if it does not exist.

fn list<'life0, 'life1, 'async_trait>( &'life0 self, workflow_id: Option<&'life1 str>, ) -> Pin<Box<dyn Future<Output = Result<Vec<WorkflowCheckpoint>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, FileCheckpointStorage: 'async_trait,

List checkpoints, optionally filtered by workflow id.

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, checkpoint_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, FileCheckpointStorage: 'async_trait,

Delete a checkpoint by id, returning whether it existed.

impl Clone for FileCheckpointStorage

fn clone(&self) -> FileCheckpointStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.
