Enum ForkError 

#[non_exhaustive]
pub enum ForkError {
    Unsupported,
    Inactive,
    MissingActivation,
    ChainMismatch,
    DuplicateFork,
    NonMonotonicForkOrder,
}

Fork selection or activation 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.

Unsupported

The selected fork is absent from the supplied chain spec.

Inactive

The selected fork is not active for the supplied validation context.

MissingActivation

Fork activation data is incomplete.

ChainMismatch

A fork spec was supplied for a different chain.

DuplicateFork

The chain spec contains the same hardfork more than once.

NonMonotonicForkOrder

The chain spec hardfork entries are not in chronological order.

Implementations

impl ForkError

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

Stable machine-readable error code.

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

Stable human-readable error message.

Trait Implementations

impl Clone for ForkError

fn clone(&self) -> ForkError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ForkError

impl Debug for ForkError

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

Formats the value using the given formatter.

impl Display for ForkError

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

Formats the value using the given formatter.

impl Eq for ForkError

impl PartialEq for ForkError

fn eq(&self, other: &ForkError) -> 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.
