*first-try* clj

*last-try* clj

*try* clj

always clj

(always x)

:return? option (default): any return value indicates success

default-options clj

double clj

(double x)

decay option: 2^n

exponential clj

(exponential x)

decay option: e^n

falsey? clj

(falsey? x)

:return? option: only falsey return values indicate success

golden-ratio clj

(golden-ratio x)

decay option: φ^n

init-options clj

(init-options options)

parse clj

(parse arg & args)

internal function that parses arguments into usable bits

resolve-catch clj

(resolve-catch options)

internal function that resolves the value of the :catch in options to a collection of exceptions to catch

resolve-decay clj

(resolve-decay {d :decay :as options})

internal function that resolves the value of :decay in options to a decay strategy: a function that accepts a current time delay milliseconds in and returns a new time delay milliseconds

resolve-keyword clj

(resolve-keyword k)

resolves k as a function named in this namespace

resolve-return clj

(resolve-return {r :return? :as options})

internal function that resolves the value of :return? in options to a return? filter: a function that accepts a candidate return value and returns truthy to approve it being returned or falsey to request a retry.

retry clj

(retry options f)

internal function that will actually retry with the specified options

truthy? clj

(truthy? x)

:return? option: only truthy return values indicate success

try-again? clj

(try-again? options error)

internal function that determines whether we try again

try-try-again clj

(try-try-again fn)

(try-try-again options fn)

(try-try-again fn & args)

(try-try-again options fn & args)

if at first you don't succeed, intelligent retry trampolining

update-sleep clj

(update-sleep options)

internal function that updates sleep with the decay function

update-tries clj

(update-tries options)

internal function that updates the number of tries that remain
