Expand description

MutationLog 存储后端 SPI。

独立于 CheckpointStore，允许不同的持久化策略。

Required Methods§

Source

fn append<'life0, 'async_trait>( &'life0 self, entry: MutationLogEntry, ) -> Pin<Box<dyn Future<Output = Result<(), CheckpointStoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

追加一条 mutation 日志。

Source

fn replay<'life0, 'life1, 'async_trait>( &'life0 self, trace_id: &'life1 TraceId, from_step: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<MutationLogEntry>, CheckpointStoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

重放 trace 从指定步骤开始的 mutation 日志。

Source

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

截断 trace 的旧日志，保留从指定步骤开始的。

Provided Methods§

Source

fn append_batch<'life0, 'async_trait>( &'life0 self, entries: Vec<MutationLogEntry>, ) -> Pin<Box<dyn Future<Output = Result<(), CheckpointStoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

批量追加 mutation 日志。

Dyn Compatibility§

This trait is dyn compatible.

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