Module error 

Error types for ExecutionClient operations.

Retry Semantics

Use ClientError::is_transient to determine if an operation should be retried. Transient errors (connectivity issues, rate limits) may succeed on retry with appropriate backoff. Non-transient errors (invalid instrument, insufficient balance) will fail identically on retry — the caller must change the request.

The is_transient() method is the stable contract for retry decisions. Prefer it over pattern matching on specific variants, as the internal taxonomy may evolve while is_transient() semantics remain stable.
