Enum ChainStateError 

pub enum ChainStateError {
    OrphanBlock,
    ValidationFailed(ConnectBlockError),
    IndexError(BlockIndexError),
    MissingBlockData(BlockHash),
    ReorgFailed {
        disconnected: u32,
        reason: Box<ConnectBlockError>,
    },
    CorruptedIndex(BlockHash),
    NoForkPoint,
}

Errors that can occur during chain state operations.

Variants

OrphanBlock

The block’s parent is unknown (orphan block).

ValidationFailed(ConnectBlockError)

The block failed contextual validation.

IndexError(BlockIndexError)

The block index rejected the header.

MissingBlockData(BlockHash)

A block needed for reorg is missing from our block store.

ReorgFailed

Reorg failed — the chain state may be inconsistent.

Fields

disconnected: u32

How far we got disconnecting before the error.

reason: Box<ConnectBlockError>

The error that stopped the reorg.

CorruptedIndex(BlockHash)

Block index is missing an entry that should exist (corrupted state).

NoForkPoint

Could not find fork point during reorg (no shared ancestor).

Trait Implementations

impl Debug for ChainStateError

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

Formats the value using the given formatter.

impl Display for ChainStateError

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

Formats the value using the given formatter.

impl Error for ChainStateError

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.
