Trait implemented by durable journals.

Required Methods§

Source

fn append<'life0, 'life1, 'async_trait>( &'life0 self, record: &'life1 MemoryRecord, ) -> Pin<Box<dyn Future<Output = MemoryResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Appends a record to the journal.

Source

fn tail<'life0, 'async_trait>( &'life0 self, limit: usize, ) -> Pin<Box<dyn Future<Output = MemoryResult<Vec<MemoryRecord>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the most recent limit records, ordered oldest to newest.

Source

fn clear<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = MemoryResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Clears the journal contents.
