Expand description

Checkpoint 存储后端 SPI — bytes in / bytes out。

存储层无需知道 State 类型或序列化格式，只操作 CheckpointBlob。 通过 TypedCheckpointStore 组合 Codec 实现类型化的 save/load。

Required Methods§

Source

fn save_with_trace<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, blob: &'life2 CheckpointBlob, ) -> 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 CheckpointBlob 并关联 trace_id。

Source

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

加载指定 ID 的 CheckpointBlob。

Source

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

加载 trace 最新的 CheckpointBlob。

Source

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,

列出 trace 的所有 CheckpointId（按时间倒序）。

Source

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,

删除指定 ID 的 Checkpoint。

Source

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,

修剪 trace 的旧 Checkpoint，保留最新的 keep 个。

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
