}

Generic error codes for common scenarios.

Use these when a domain-specific error code is not available.

Error indexes

The six historical variants keep their original indexes (0-6) so existing internalCode values stay stable. Every variant added later uses its HTTP status code as index, which makes the internal code self-describing (UnprocessableEntity -> 1422, TooManyRequests -> 1429).

Other is the catch-all for any status without a dedicated variant: it carries the status verbatim so nothing is ever silently degraded to 500.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Trait Implementations

impl Clone for GenericErrorCode

fn clone(&self) -> GenericErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GenericErrorCode

impl CqrsErrorCode for GenericErrorCode

fn domain() -> &'static str

The domain this error belongs to (e.g., “tenant”, “license”)

fn domain_prefix() -> u16

Domain prefix for internal codes (0-9) Each domain gets a unique prefix.

fn error_index(&self) -> u16

Unique error index within the domain (0-999)

fn http_status(&self) -> StatusCode

HTTP status code for this error

fn internal_code(&self) -> u16

Full internal code: domain_prefix * 1000 + error_index Example: Tenant (4) + NotFound (1) = 4001

fn code_string(&self) -> String

String representation of the error code for JSON serialization Format: DOMAIN_ERROR_NAME (e.g., “PLAN_NOT_FOUND”)

fn error(&self, message: impl Into<String>) -> CqrsError

where Self: Sized,

Create a CqrsError from this code with a message

impl Debug for GenericErrorCode

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

Formats the value using the given formatter.

impl Display for GenericErrorCode

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

Formats the value using the given formatter.

impl Eq for GenericErrorCode

impl Error for GenericErrorCode

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<StatusCode> for GenericErrorCode

fn from(status: StatusCode) -> Self

Maps an HTTP status to its dedicated variant, falling back to GenericErrorCode::Other — which preserves the status — instead of degrading unknown statuses to 500.

impl PartialEq for GenericErrorCode

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

Equality operator ==.

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

Inequality operator !=.
