Class: Premium820BuildError

Thrown by "./build-820.js".build820 when the supplied premium spec cannot be emitted as a conformant, self-consistent 820. Carries a stable code for programmatic narrowing. Deliberately does NOT extend X12ParseError or X12BuildError - the domain-refusal distinction matters at the type level.

Example​

import { Premium820BuildError } from "@cosyte/x12";
try {
  build820(spec);
} catch (err) {
  if (err instanceof Premium820BuildError) {
    // err.code is one of PREMIUM_820_BUILD_ERROR_CODES
  }
}
