retry

A simple Go retry package and it is heavily inspired from the try package from Mat Ryer

go get github.com/swathinsankaran/retry

Usage

retry.Do with the function you want to retry along with number of retries(maxRetryAttempt) and a timeout for the entire execution(retryTimeout).

The retry package retries when it encounters any of the below events:

• Function passed returns an error.
• Execution of the function passed was unsuccessful.

The retry package returns error in the below cases:

• Function passed returns an error.
• Retry count exceeds maxRetryAttempt.
• Function execution time exceeds retryTimeout milliseconds.

Example:

import "github.com/swathinsankaran/retry"

// some codes...

err := retry.Do(func() (bool, error) {
    // code to retry goes here...
}, 10, 1)

In the above example the function will be called repeatedly until:

• error is nil.
• retries exceeds 10.
• execution time exceeds 1 millisecond.
