Enum OrmError 

#[non_exhaustive]
pub enum OrmError {
    Query(QueryError),
    Backend(BackendError),
    Capability(BackendCapabilityError),
    Cursor(CursorError),
    Signal(SignalError),
    UnknownDatabase(String),
}

Top-level ORM error.

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.

Query(QueryError)

Query-construction or result error.

Backend(BackendError)

Backend failure.

Capability(BackendCapabilityError)

Capability mismatch.

Cursor(CursorError)

A pagination cursor from the client was rejected.

Signal(SignalError)

A signal receiver failed. A failing pre_* receiver aborted the operation; a failing post_* receiver ran after the statement. Maps to HTTP 500 (ApiError: From<OrmError> falls through to internal).

UnknownDatabase(String)

A database alias is not registered in Databases.

A configuration problem (a router named an alias that was never registered, or there is no "default"), so it maps to HTTP 500.

Trait Implementations

impl Debug for OrmError

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

Formats the value using the given formatter.

impl Display for OrmError

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

Formats the value using the given formatter.

impl Error for OrmError

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.
