    },
    AlreadyTracked {
        key: ObjectKey,
        state: &'static str,
    },
}

Error type for Unit of Work operations.

Variants

CycleDetected

A dependency cycle was detected between tables.

Fields

tables: Vec<&'static str>

AlreadyTracked

An object was already tracked.

Fields

key: ObjectKey

Trait Implementations

impl Clone for UowError

fn clone(&self) -> UowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UowError

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

Formats the value using the given formatter.

impl Display for UowError

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

Formats the value using the given formatter.

impl Error for UowError

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<UowError> for Error

fn from(e: UowError) -> Self

Converts to this type from the input type.
