pub const LIGHTER_ERROR_CODE_TX_RANGE: Range<u64>;Expand description
Venue error-code range for L2 transaction failures.
Observed codes follow a domain split: 20xxx request validation, 21xxx
transaction processing (21104 invalid nonce, 21149 integrator not
approved), 30xxx WebSocket subscription state (30003 “Already
Subscribed”). Bare error frames are attributed to in-flight sendTx
requests only when the code falls in this range.
