Functions

func CalculateBackoff

func CalculateBackoff(retry int) time.Duration

CalculateBackoff calculates the next delay for retry with exponential backoff and jitter. The baseDelay is the initial delay duration, which is exponentially increased on each retry. The jitterFactor adds randomness to the delay to avoid simultaneous retries (thundering herd problem). The delay is capped at maxDelay to prevent excessive wait times.

func ParseRateLimitHeaders

func ParseRateLimitHeaders(resp *http.Response, log logger.Logger) time.Duration

ParseRateLimitHeaders parses common rate limit headers and adjusts behavior accordingly. It handles both Retry-After (in seconds or HTTP-date format) and X-RateLimit-Reset headers.
