Enum EventStatus 

pub enum EventStatus {
    Pending,
    Processing,
    Sent,
}

Lifecycle stage of an outbox Event.

A row moves forward through the variants and never steps backwards on a happy path:

Pending → Processing → Sent

When the sqlx feature is enabled, this enum maps to a Postgres type named status with PascalCase variant names.

Variants

Pending

Newly written row awaiting a worker. Includes both freshly inserted events and rows whose processing lock expired (making them eligible for retry).

Processing

A worker has claimed the row and is currently attempting to publish it. The lock is held until Event::locked_until.

Sent

The event has been successfully published to the transport. Rows in this state are eventually removed by the garbage collector.

Trait Implementations

impl Clone for EventStatus

fn clone(&self) -> EventStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'r> Decode<'r, Postgres> for EventStatus

fn decode( value: PgValueRef<'r>, ) -> Result<Self, Box<dyn Error + Send + Sync + 'static>>

Decode a new value of this type using a raw value from the database.

impl<'q, DB: Database> Encode<'q, DB> for EventStatus

where &'q str: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

impl PartialEq for EventStatus

fn eq(&self, other: &EventStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PgHasArrayType for EventStatus

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl StructuralPartialEq for EventStatus

impl Type<Postgres> for EventStatus

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &<DB as Database>::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
