Enum RepositoryError 

pub enum RepositoryError {
    Conflict {
        id: i64,
        expected_version: i64,
        actual_version: Option<i64>,
    },
}

Typed errors returned by generated repository methods.

Distinct from crate::AutumnError so callers can match on the variant without parsing an HTTP status code.

Variants

Conflict

Two writers raced on the same row.

Returned by generated update/save methods when the #[lock_version] field no longer matches the value the client sent — meaning another replica committed a write in the meantime.

Map this to 409 Conflict via crate::AutumnError::conflict.

Fields

id: i64

Primary key of the contested record.

expected_version: i64

The version the client read and expected to still be current.

actual_version: Option<i64>

The version actually stored when the conflict was detected, or None if the row was deleted between the read and the write.

Trait Implementations

impl Clone for RepositoryError

fn clone(&self) -> RepositoryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepositoryError

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

Formats the value using the given formatter.

impl Display for RepositoryError

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

Formats the value using the given formatter.

impl Error for RepositoryError

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.
