## What it is
A simple Go library providing a retry mechanism for retrying failing operations with configurable attempts, delays, and backoff strategies. It offers a minimal API including reusable retriers and data-returning retry helpers.

## Use cases
- retry failed http requests in go
- add exponential backoff to flaky network calls
- retry database or api operations with configurable attempts
- wrap unreliable function calls with automatic retries
- reuse a configured retrier for high-frequency operations

## When to choose
- you need a simple, well-adopted retry library for Go
- you want configurable delays, backoff, and attempt limits with a tiny API
- you need a data-returning retry helper or reusable retrier instances

## When to avoid
- you need advanced circuit-breaking or bulkhead patterns beyond simple retries
- you prefer a more feature-rich backoff framework like cenkalti/backoff
- you want an actively developed fork with recent correctness improvements

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, concurrency
- domain: developer-tools, backend, apis
- platform: go, cross-platform
- tags: retry, backoff, resilience, golang-library
