Required Methods§

Source

fn save<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, branch_id: &'life1 str, events: &'life2 [GraphEventRecord], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Atomically replace one branch generation. Intended for a single writer.

Source

fn load<'life0, 'life1, 'async_trait>( &'life0 self, branch_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<GraphEventRecord>>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

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

Provided Methods§

Source

fn save_if_head<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _branch_id: &'life1 str, _expected_head: Option<&'life2 str>, _events: &'life3 [GraphEventRecord], ) -> Pin<Box<dyn Future<Output = Result<GraphSaveOutcome>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Compare the persisted head and publish an extending generation atomically.

Dyn Compatibility§

This trait is dyn compatible.

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