Signature, parameters, and return type

/** Stable machine-readable codes. Never emitted for data problems. */
type FormatErrorCode =
/** Configuration error: `timeZone` is not 'UTC' | 'device' | a zone name the
 *  runtime's Intl accepts. A programmer can fix this. */
'ERR_TIMEZONE_INVALID'
/** Configuration error: `locale` is not a tag the runtime's Intl accepts
 *  (`'ko_KR'`, `'en US'`, `'ko-KR-'`). `FormatLocale` accepts any string, so
 *  this is the runtime half of that axis. A programmer can fix this. */
 | 'ERR_LOCALE_INVALID'
/** Configuration error: `minimumFractionDigits`/`maximumFractionDigits` is not
 *  an integer in 0–100, or the minimum exceeds the maximum. A programmer can
 *  fix this. */
 | 'ERR_FRACTION_DIGITS_INVALID'
/** Environment error: the runtime's Intl failed this package's self-test —
 *  it ignores the `timeZone` option, or ignores `hourCycle`/`hour12`.
 *  A programmer cannot fix this; ask {@link canFormatTimeZone} up front. */
 | 'ERR_INTL_UNUSABLE'
/** Environment error: a single-field formatter produced a non-numeric or
 *  out-of-range string for this specific zone. */
 | 'ERR_INTL_FIELD_OUTPUT';
