Struct InMemoryQueueStore 

pub struct InMemoryQueueStore { /* private fields */ }

Pure in-memory QueueStore for tests and single-process pilot deployments. Not durable across restarts.

Implementations

impl InMemoryQueueStore

pub fn new() -> Self

Create an empty in-memory store.

Trait Implementations

impl Default for InMemoryQueueStore

fn default() -> Self

Returns the “default value” for a type.

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

Fetch up to limit pending messages whose next_retry is <= now.

fn recover_stale_inflight<'life0, 'async_trait>( &'life0 self, now: i64, ) -> Pin<Box<dyn Future<Output = Result<u64, StoreError>> + Send + 'async_trait>>

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

Reset inflight messages older than ~10 minutes back to pending (crash-recovery). Returns rows affected.

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

Mark a message as currently being delivered.

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

Mark a delivery attempt as failed; the message goes back to pending with an incremented attempts and a next_retry of next_retry.

fn mark_bounced<'life0, 'life1, 'async_trait>( &'life0 self, id: i64, error: &'life1 str, now: i64, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

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

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

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

fn list_recent<'life0, 'async_trait>( &'life0 self, limit: i32, ) -> Pin<Box<dyn Future<Output = Result<Vec<QueuedMessage>, StoreError>> + Send + 'async_trait>>

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

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

Delete a single pending message identified by RFC 5322 Message-ID and sender (so a user can only cancel their own undelivered messages).

fn retry_message<'life0, 'async_trait>( &'life0 self, id: i64, now: i64, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>

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