Enum Error 

pub enum Error {
    Capability(CapabilityError),
    Policy(PolicyError),
    Rights(RightsError),
    Step(StepError),
    State(StateError),
    Kernel(KernelError),
}

Unified error type for lion-core operations.

Collects all domain error types so callers only need to handle a single error type.

Variants

Capability(CapabilityError)

Capability operation error (invalid holder, empty rights, etc.)

Policy(PolicyError)

Policy operation error

Rights(RightsError)

Rights operation error

Step(StepError)

Step execution error

State(StateError)

State operation error

Kernel(KernelError)

Kernel operation error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

Available on non-extract only.

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.
