Implementations

impl DydxError

pub fn is_sequence_mismatch(&self) -> bool

Returns true if this error is a sequence mismatch (code=32 or code=104 with sequence hint).

Sequence mismatch occurs when:

• Multiple transactions race for the same sequence number
• A transaction was submitted but not yet included in a block
• The local sequence counter is out of sync with chain state

On dYdX v4, sequence mismatches can manifest as either:

• code=32: Standard Cosmos SDK “account sequence mismatch”
• code=104: dYdX authenticator “signature verification failed; please verify sequence”

These errors are typically recoverable by resyncing the sequence from chain and rebuilding the transaction.

pub fn is_tx_in_mempool(&self) -> bool

Returns true if this error indicates the transaction is already in the mempool (code=19).

This is benign for short-term orders – the transaction was already accepted by the mempool on a previous submission and will be processed. Callers can safely treat this as success.

pub fn is_cancel_already_in_memclob(&self) -> bool

Returns true if this error indicates a duplicate cancel already in the memclob (code=9).

dYdX rejects cancel messages when an existing cancel for the same order has a greater-than-or-equal GoodTilBlock. The original cancel will be processed.

pub fn is_order_does_not_exist(&self) -> bool

Returns true if this error indicates the order to cancel does not exist (code=3006).

The order was already filled, expired, or previously cancelled.

pub fn is_benign_cancel_error(&self) -> bool

Returns true if this error is benign for short-term cancel operations.

Benign cancel errors occur during overlapping cancel waves (common in grid MM):

• code=19: Transaction already in mempool cache (duplicate tx bytes)
• code=9: Cancel already exists in memclob with >= GoodTilBlock
• code=3006: Order to cancel does not exist (already filled/expired/cancelled)

pub fn is_transient(&self) -> bool

Returns true if this error is likely transient and worth retrying.

Transient errors include:

• Sequence mismatch (recoverable by resync)
• Network timeouts
• Temporary node unavailability

Trait Implementations

impl Debug for DydxError

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

Formats the value using the given formatter.

impl Display for DydxError

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

Formats the value using the given formatter.

impl Error for DydxError

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
