Enum authzen_core::ActionError

pub enum ActionError<E1, E2, E3> {
    Authz(E1),
    Storage(E2),
    TransactionCache(E3),
}

Represents the possible sources of error when performing an action which requires authorization.

Variants

Authz(E1)

Wraps an error returned from a DecisionMaker when the subject is either not authorized to perform an action or some other issue occurs while communicating with the DecisionMaker.

Storage(E2)

Wraps an error returned from a StorageClient when the subject has been authorized to perform an action but there an error occurs while actually performing the error. Examples of this include network errors while communicating with an api or database, unique constraint violations raised by a database, etc.

TransactionCache(E3)

Wraps an error returned from a TransactionCache when updating the transaction cache after a successful performance of the action.

Trait Implementations

impl<E1: Clone, E2: Clone, E3: Clone> Clone for ActionError<E1, E2, E3>

fn clone(&self) -> ActionError<E1, E2, E3>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E1: Debug, E2: Debug, E3: Debug> Debug for ActionError<E1, E2, E3>

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

Formats the value using the given formatter.

impl<E1, E2, E3> Error for ActionError<E1, E2, E3>where E1: Debug + Display + Error + 'static, E3: Debug + Display + Error + 'static, E2: Debug + Display + Error + 'static, ActionError<E1, E2, E3>: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
