}

Errors due to the fact that the uncle rule is not respected.

Variants

OverCount

The number of block uncles exceeds limit.

Fields

max: u32

The limited number of block uncles.

actual: u32

The actual number of block uncles.

InvalidNumber

There is an uncle whose number is greater than or equal to current block number.

InvalidTarget

There is an uncle who belongs to a different epoch from the current block.

InvalidDifficultyEpoch

There is an uncle who belongs to a different epoch from the current block.

ProposalsHash

There is an uncle whose proposals-hash does not match with the calculated result.

ProposalDuplicate

There is an uncle whose proposals have duplicated items.

Duplicate(Byte32)

There are duplicated uncles in the current block.

DoubleInclusion(Byte32)

There is an uncle that has already been included before.

DescendantLimit

The depth of uncle descendant exceeds limit.

ExceededMaximumProposalsLimit

The number of uncle proposals exceeds limit.

Trait Implementations

impl Clone for UnclesError

fn clone(&self) -> UnclesError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnclesError

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

Formats the value using the given formatter.

impl Display for UnclesError

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

Formats the value using the given formatter.

impl Error for UnclesError

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<UnclesError> for BlockError

fn from(error: UnclesError) -> Self

Converts to this type from the input type.

impl From<UnclesError> for Error

fn from(error: UnclesError) -> Self

Converts to this type from the input type.

impl PartialEq for UnclesError

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