Result Flow

Appearance

Batch Processing ​

Batch tools make the difference between item-level status and whole-collection status explicit.

php
use Maxiviper117\ResultFlow\Result;

$results = Result::mapItems($rows, fn (array $row, string $key) => validateRow($row, $key));

The batch families ​

  • mapItems(...) returns one Result per input item.
  • mapAll(...) fails fast on the first failure and returns keyed success values.
  • mapCollectErrors(...) processes everything and returns keyed failures.
  • combine(...) and combineAll(...) aggregate already-built Result values.

What to remember ​

  • mapAll(...) and combine(...) are fail-fast.
  • mapCollectErrors(...) and combineAll(...) collect all failures; combineAll(...) does not return success values if any input fails.
  • keys are preserved where the API says they are preserved.
