Errors that can occur in block sequence operations.

Variants

OrderingViolation

A known block_id appeared after an unknown block_id in extend_block_ids.

Fields

known_id: BlockId

new_id: BlockId

known_index: usize

first_new_index: usize

PositionMismatch

The position embedded in a sequence hash didn’t match the expected position.

Fields

expected: usize

actual: u64

block_id: BlockId

DuplicateBlockId

A block_id already exists in one of the collections.

Fields

block_id: BlockId

TokenExtension(TokenBlockError)

Error from underlying token block operations.

Trait Implementations

impl Debug for BlockSequenceError

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

Formats the value using the given formatter.

impl Display for BlockSequenceError

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

Formats the value using the given formatter.

impl Error for BlockSequenceError

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<TokenBlockError> for BlockSequenceError

fn from(source: TokenBlockError) -> Self

Converts to this type from the input type.
