Enum ProtocolError 

#[non_exhaustive]
pub enum ProtocolError {
    Feature(FeatureError),
    Fork(ForkError),
    InvalidStateTransition,
}

Protocol validation failure.

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.

Feature(FeatureError)

A feature is disabled or unsupported for the selected operation.

Fork(ForkError)

Fork context is missing, unsupported, or inactive.

InvalidStateTransition

A validation state transition was attempted out of order.

Implementations

impl ProtocolError

pub const fn code(self) -> &'static str

Stable machine-readable error code.

pub const fn message(self) -> &'static str

Stable human-readable error message.

pub const fn category(self) -> ProtocolErrorCategory

Stable high-level category for policy decisions.

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> ProtocolError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtocolError

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Eq for ProtocolError

impl PartialEq for ProtocolError

fn eq(&self, other: &ProtocolError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
