Errors concerning log filtering.

Variants

InvalidEpochNumber

Fields

from_epoch: u64

to_epoch: u64

Filter has wrong epoch numbers set.

InvalidBlockNumber

Fields

from_block: u64

to_block: u64

Filter has wrong block numbers set.

OutOfBoundEpochNumber

Fields

to_epoch: u64

max_epoch: u64

EpochNumberGapTooLarge

Fields

from_epoch: u64

to_epoch: u64

max_gap: u64

BlockNumberGapTooLarge

Fields

from_block: u64

to_block: u64

max_gap: u64

UnableToVerify

Fields

epoch: u64

latest_verifiable: u64

Roots for verifying the requested epochs are unavailable.

UnknownBlock

Fields

hash: H256

The block requested does not exist

EpochAlreadyPruned

Fields

epoch: u64

min: u64

Epoch cannot be served as it was already pruned from db on a full node

BlockAlreadyPruned

Fields

block_hash: H256

Block cannot be served as it was already pruned from db on a full node

BlockNotExecutedYet

Fields

block_hash: H256

Block has not been executed yet

PivotChainReorg

Fields

epoch: u64

from: H256

to: H256

There was a pivot chain reorganization during log filtering

Custom(String)

Filter error with custom error message (e.g. timeout)

Trait Implementations

impl Clone for FilterError

fn clone(&self) -> FilterError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilterError

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

Formats the value using the given formatter.

impl Display for FilterError

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

Formats the value using the given formatter.

impl Error for FilterError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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<String> for FilterError

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for FilterError

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

This method tests for self and other values to be equal, and is used by ==.

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

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