(delay-exp retry-count)
(delay-exp base retry-count)
Calculate an exponential delay in millis.
base - the base number to scale (default 100) retry-count - the number of previous attempts
Calculate an exponential delay in millis. base - the base number to scale (default 100) retry-count - the number of previous attempts
(delay-linear factor retry-count)
Calculate a linear delay in millis.
factor - the linear factor to use retry-count - the number of previous attempts
Calculate a linear delay in millis. factor - the linear factor to use retry-count - the number of previous attempts
(init {_r? :com.potetm.fusebox.cljs.retry/retry?
_d :com.potetm.fusebox.cljs.retry/delay
:as spec})
Initialize a retry.
spec is map containing: ::retry? - A predicate called after an exception to determine whether body should be retried. Takes three args: eval-count, exec-duration-ms, and the exception/failing value. ::delay - A function which calculates the delay in millis to wait prior to the next evaluation. Takes three args: eval-count, exec-duration-ms, and the exception/failing value. ::success? - (Optional) A function which takes a return value and determines whether it was successful. If false, body is retried. Defaults to (constantly true).

(jitter jitter-factor delay)
Randomly jitter a given delay.
jitter-factor - the decimal jitter percentage, between 0 and 1 delay - the base delay in millis
