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_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

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.
