GraphPersistence trait for storing and loading graph definitions

Required Methods§

Source

fn save<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 str, definition: &'life2 GraphDefinition, ) -> Pin<Box<dyn Future<Output = Result<(), PersistenceError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Save a graph definition with the given ID

Source

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

Load a graph definition by ID

Source

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

Delete a graph definition by ID

Source

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

Check if a graph definition exists

Source

fn list<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, PersistenceError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

List all stored graph IDs

Dyn Compatibility§

This trait is dyn compatible.

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