Enum OutboxError 

pub enum OutboxError {
    Db(Error),
    InvalidSchema(String),
    Publish(String),
    Exhausted(String),
}

Errors from staging, relaying, or deduping durable events.

Variants

Db(Error)

A database error.

InvalidSchema(String)

A schema name that is not a safe SQL identifier (^[a-z_][a-z0-9_]*$).

Publish(String)

The relay’s publish callback failed for a record; the row is left unpublished for retry.

Exhausted(String)

The relay’s publish callback GAVE UP on a record — its transport exhausted its own retries or dead-lettered it, and will not deliver this event however many times it is handed over.

Distinct from OutboxError::Publish on purpose. A transport that has given up used to have no way to say so: returning Ok marked the row published, which reads as delivered while the effect was dropped, and returning Publish re-handed the same doomed record on every pass forever. This variant marks the row dead — not published, visible in the table, and re-emittable once the cause is fixed.

Trait Implementations

impl Debug for OutboxError

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

impl Error for OutboxError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for OutboxError

fn from(source: Error) -> Self

Converts to this type from the input type.
