This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. promiseRetry executes an async operation and resolves with its returned value when successful on first attempt
  2. promiseRetry retries an operation when retry callback is invoked with an error until it succeeds
  3. promiseRetry provides 1-based attempt numbers to the operation callback on each retry attempt
  4. promiseRetry rejects with the last error when the configured retries count is exhausted
  5. promiseRetry immediately rejects without retrying when an unhandled error is thrown without calling retry
  6. promiseRetry accepts retry options as either the first or second argument
  7. promiseRetry applies exponential backoff with custom minTimeout and factor settings
  8. promiseRetry handles synchronous values returned from the operation function
