This two packages implement two super simple functions:

• Package limiter does what is says, it wraps a function and runs it, limiting the number of goroutunes that can be run at the same time ( number can be toogle with a simple exposed variable ).

• Package retry does what is says as well if a function calls fails ( resulting in a error rather than a nil value ), runs is again. As arguments takes also the number of retries and a sleep value specified in milliseconds.

The package limiter in basically a shameless copy from this golang talk, all the credits go to the guy https://www.youtube.com/watch?v=yeetIgNeIkc. Tough I am almost sure I am going to rewrite it in a near future. This is what a call nice to have middleware.
