Enum MergePlanResolutionError 

pub enum MergePlanResolutionError {
    DuplicateConflict(ConflictKey),
    MissingDriver(ConflictKey),
    Driver(DriverError),
    StaleEffectful,
}

Merge-plan resolution failure.

Variants

DuplicateConflict(ConflictKey)

The immutable plan contains the same semantic conflict more than once.

MissingDriver(ConflictKey)

No registered driver accepts one conflict.

Driver(DriverError)

Driver execution failed.

StaleEffectful

Replanning invalidated an effectful or deferred decision.

impl Eq for MergePlanResolutionError

impl Error for MergePlanResolutionError

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
