Retryer

The tiny library for retrying any action.

Motivation

I needed in some similar behavior in the one of project. A half of a minute of googling showed nothing. That's why the decision to extract the library was made.

Plans

Add cancellation context.

Usages

Retry number of times

Retry(10).
    ExecuteBool(func() bool {
        counter++

        if counter == 5 {
            return true
        }

        return false
    })

Retry with error

Retry(10).
    ExecuteError(func() error {
        conn, err := MakeConnection()

        return err
    })

Retry with wait

RetryAndWait([]time.Duration{1000 * time.Millisecond, 1000 * time.Millisecond}).
    ExecuteError(func() error {
        conn, err := MakeConnection()

        return err
    })

retry with wait forever

RetryAndWaitForever(func(attempt int) time.Duration { return time.Duration(attempt*100) * time.Millisecond }).
    ExecuteError(func() error {
        conn, err := MakeConnection()

        return err
    })
