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: BlockNumber

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: BlockHash

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: BlockNumber

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: BlockHash

The block hash that could not be found.

BlockBufferingFailed

Thrown if the block failed to buffer

Fields

block_hash: BlockHash

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

Formats the value using the given formatter.

impl Display for BlockchainTreeError

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

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) -> Self

Converts to this type from the input type.

impl From<BlockchainTreeError> for InsertBlockErrorKind

fn from(source: BlockchainTreeError) -> Self

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
