State Repository trait

Generic parameters:

• C - Command
• S - State
• Version - Version
• Error - Error

Required Methods

fn fetch_state<'life0, 'life1, 'async_trait>( &'life0 self, command: &'life1 C ) -> Pin<Box<dyn Future<Output = Result<Option<(S, Version)>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetches current state, based on the command.

fn save<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, state: &'life1 S, version: &'life2 Option<Version> ) -> Pin<Box<dyn Future<Output = Result<(S, Version), Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Saves state.
