Enum BlockIndexError 

pub enum BlockIndexError {
    OrphanHeader,
    DuplicateBlock,
    CheckpointMismatch {
        height: u32,
        expected: String,
        got: String,
    },
    TargetExceedsPowLimit,

}

Errors from block index operations

Variants

OrphanHeader

The parent block hash is not in the index

DuplicateBlock

The block is already known

CheckpointMismatch

A header at a checkpoint height does not match the expected hash

Fields

height: u32

expected: String

got: String

TargetExceedsPowLimit

The header’s target (nBits) exceeds the network’s proof-of-work limit

InsufficientProofOfWork

The block hash does not meet the proof-of-work target

Trait Implementations

impl Clone for BlockIndexError

fn clone(&self) -> BlockIndexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockIndexError

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

Formats the value using the given formatter.

impl Display for BlockIndexError

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

Formats the value using the given formatter.

impl Error for BlockIndexError

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<BlockIndexError> for ChainStateError

fn from(e: BlockIndexError) -> Self

Converts to this type from the input type.

impl PartialEq for BlockIndexError

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