Struct InMemoryCheckpointStore 

pub struct InMemoryCheckpointStore { /* private fields */ }

基于内存的 Checkpoint 存储后端。

通过 save_with_trace() 关联 trace_id，或在存储层组织关联。

Implementations

impl InMemoryCheckpointStore

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl CheckpointStore for InMemoryCheckpointStore

fn save_with_trace<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, checkpoint: &'life2 Checkpoint, ) -> Pin<Box<dyn Future<Output = Result<(), CheckpointStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

保存 Checkpoint 并关联 trace_id。

fn load<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 CheckpointId, ) -> Pin<Box<dyn Future<Output = Result<Option<Checkpoint>, CheckpointStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn load_latest<'life0, 'life1, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, ) -> Pin<Box<dyn Future<Output = Result<Option<Checkpoint>, CheckpointStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn list<'life0, 'life1, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, ) -> Pin<Box<dyn Future<Output = Result<Vec<CheckpointId>, CheckpointStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

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

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn prune<'life0, 'life1, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, keep: usize, ) -> Pin<Box<dyn Future<Output = Result<usize, CheckpointStoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

impl Default for InMemoryCheckpointStore

fn default() -> InMemoryCheckpointStore

Returns the “default value” for a type.
