Trait Implementations

impl Clone for PostgresJournal

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Journal for PostgresJournal

fn acquire_lease<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, run_id: &'life1 str, owner: &'life2 str, ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<Result<(), LeaseHolder>, JournalError>> + Send + 'async_trait>>

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

Leases use the database clock, so worker clock skew does not matter.

fn append<'life0, 'life1, 'async_trait>( &'life0 self, event: &'life1 Event, ) -> Pin<Box<dyn Future<Output = Result<(), JournalError>> + Send + 'async_trait>>

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

fn renew_lease<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, run_id: &'life1 str, owner: &'life2 str, ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<bool, JournalError>> + Send + 'async_trait>>

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

Extend a lease this owner holds. false means it was lost.

fn release_lease<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, run_id: &'life1 str, owner: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), JournalError>> + Send + 'async_trait>>

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

fn load<'life0, 'life1, 'async_trait>( &'life0 self, run_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<Event>, JournalError>> + Send + 'async_trait>>

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