Various error cases that can occur when a block violates tree assumptions.

Variants

PendingBlockIsFinalized

Thrown if the block number is lower than the last finalized block number.

Fields

last_finalized: u64

The block number of the last finalized block.

BlockSideChainIdConsistency

Thrown if no side chain could be found for the block.

Fields

chain_id: u64

The internal identifier for the side chain.

CanonicalChain

Thrown if a canonical chain header cannot be found.

Fields

block_hash: FixedBytes<32>

The block hash of the missing canonical chain header.

BlockNumberNotFoundInChain

Thrown if a block number cannot be found in the blockchain tree chain.

Fields

block_number: u64

The block number that could not be found.

BlockHashNotFoundInChain

Thrown if a block hash cannot be found in the blockchain tree chain.

Fields

block_hash: FixedBytes<32>

The block hash that could not be found.

BlockBufferingFailed

Thrown if the block failed to buffer

Fields

block_hash: FixedBytes<32>

The block hash of the block that failed to buffer.

GenesisBlockHasNoParent

Thrown when trying to access genesis parent.

Trait Implementations

impl Clone for BlockchainTreeError

fn clone(&self) -> BlockchainTreeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockchainTreeError

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

Formats the value using the given formatter.

impl Display for BlockchainTreeError

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

Formats the value using the given formatter.

impl Error for BlockchainTreeError

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 #99301)

Provides type-based access to context intended for error reports.

impl From<BlockchainTreeError> for CanonicalError

fn from(source: BlockchainTreeError) -> CanonicalError

Converts to this type from the input type.

impl From<BlockchainTreeError> for InsertBlockErrorKind

fn from(source: BlockchainTreeError) -> InsertBlockErrorKind

Converts to this type from the input type.

impl PartialEq for BlockchainTreeError

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

impl Copy for BlockchainTreeError

impl Eq for BlockchainTreeError

impl StructuralPartialEq for BlockchainTreeError
