## Description

This is a Go library providing a framework for managing repetitive task execution and implementing exponential backoff strategies. It serves as a concurrency tool designed to prevent system overload during failures by retrying operations with increasing delays.

The project implements a retry strategy framework that manages attempt limits and timeouts during unstable network or system calls. It specifically provides an implementation of the exponential backoff algorithm to handle failing operations.

The library covers reliability patterns for mitigating transient failures and service outages, including the management of API request retries and inter-service communication in microservices. It handles transient error recovery and distributed system resilience through automated re-execution of failing tasks.
