initclj

(init {_r? :com.potetm.fusebox.retry/retry?
       _d :com.potetm.fusebox.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. The last failing value can be found under the ::retry/val key in the thrown ex-info's data. Defaults to (constantly true).
