        expected: u64,
        got: u64,
    },
    SequenceGap {
        expected: u64,

}

Errors from chain validation.

Variants

OriginMismatch

Event’s origin_hash doesn’t match the chain’s entity.

Fields

expected: u64

Expected origin_hash.

got: u64

Actual origin_hash.

SequenceGap

Sequence number is not prev + 1.

Fields

expected: u64

Expected sequence number.

got: u64

Actual sequence number.

ParentHashMismatch

parent_hash doesn’t match xxh3(prev_link ++ prev_payload).

Fields

expected: u64

Expected parent hash.

got: u64

Actual parent hash.

Trait Implementations

impl Clone for ChainError

fn clone(&self) -> ChainError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainError

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

Formats the value using the given formatter.

impl Display for ChainError

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

Formats the value using the given formatter.

impl Error for ChainError

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 PartialEq for ChainError

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