A batch or book state that breaks the order book stream contract.

Variants

MissingLast

The batch does not end with an F_LAST delta.

SnapshotFlagMismatch

F_SNAPSHOT disagrees with the event group kind on at least one delta.

SnapshotAction(BookAction)

A snapshot delta after the leading Clear is not an Add.

ClearInIncremental

An incremental event group contains a Clear.

IncrementalBeforeSnapshot

An incremental event group arrived before the episode’s snapshot.

SequenceNotIncreasing

An incremental sequence does not exceed the previous one.

Fields

previous: u64

sequence: u64

OutputWhileClosed

Output arrived for a book that is not open.

Integrity(String)

The maintained book failed an integrity check.

TruthMismatch

The maintained book differs from venue truth.

Fields

sequence: u64

Unsynced

Verification was requested before any snapshot.

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
