Variable: FATAL_CODES

const FATAL_CODES: object

Stable string codes for every Tier-3 fatal the record parser may throw. Consumers narrow on err.code to react to specific structural failures. Renaming a code is a breaking change.

Type Declaration

ASTM_RECORD_NO_HEADER

readonly ASTM_RECORD_NO_HEADER: "ASTM_RECORD_NO_HEADER" = "ASTM_RECORD_NO_HEADER"

The first record is not an H (header) record - an ASTM message must lead with H.

ASTM_RECORD_UNDECLARED_DELIMITERS

readonly ASTM_RECORD_UNDECLARED_DELIMITERS: "ASTM_RECORD_UNDECLARED_DELIMITERS" = "ASTM_RECORD_UNDECLARED_DELIMITERS"

The H record is too short to declare the four delimiters (field/repeat/component/escape).

EMPTY_INPUT

readonly EMPTY_INPUT: "EMPTY_INPUT" = "EMPTY_INPUT"

Input was empty or whitespace-only - there is nothing to parse. Shared across layers.

Example

import { parseAstmRecords, FATAL_CODES, AstmParseError } from "@cosyte/astm";
try {
  parseAstmRecords("");
} catch (err) {
  if (err instanceof AstmParseError && err.code === FATAL_CODES.EMPTY_INPUT) {
    // handle empty input
  }
}
