Function exponentialBackoff

exponentialBackoff(maxRetries, waiter?): (<E, T>(fallback) => (<S, A>(triable) => ((set) => Optical<PromiseHkt, S, T, A, B>)))
Creates a retriable optical by exponential backoff method. It increases the delay duration (100 milliseconds) multiplied by the power of two, but its exponent stops at 23.
Parameters
- maxRetries: number
 Maximum retry counts.
- waiter: ((milliseconds) => Promise<void>) = ...
 The waiter function to delay. Defaults to setTimeout method.
 - - (milliseconds): Promise<void>
 - Parameters
 milliseconds: number
 Returns Promise<void>
Returns (<E, T>(fallback) => (<S, A>(triable) => ((set) => Optical<PromiseHkt, S, T, A, B>)))
The retriable optical.
- - <E, T>(fallback): (<S, A>(triable) => ((set) => Optical<PromiseHkt, S, T, A, B>))
