Enum CoreError 

#[non_exhaustive]
pub enum CoreError {
    Validation(ValidationError),
    Transition(TransitionError),
    Sovereignty(SovereigntyError),
}

Top-level error type for the alpe-core crate.

Aggregates all domain-specific error variants and provides From conversions for ergonomic error propagation with ?.

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.

Validation(ValidationError)

An input validation rule was violated.

Transition(TransitionError)

An invalid state machine transition was attempted.

Sovereignty(SovereigntyError)

A sovereignty / jurisdiction constraint was violated.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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<SovereigntyError> for CoreError

fn from(source: SovereigntyError) -> Self

Converts to this type from the input type.

impl From<TransitionError> for CoreError

fn from(source: TransitionError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for CoreError

fn from(source: ValidationError) -> Self
