sts assumeRole examples do not work

https://godoc.org/github.com/aws/aws-sdk-go-v2/aws/stscreds#hdr-Assume_Role

aws.NewCredentials for example doesn't exist!

I think it should be something like:

  cfg.Credentials = stscreds.NewAssumeRoleProvider(sts.New(cfg), role)
  s3svc := s3.New(cfg)

Is it possible validate your examples as part of your CI?

Thanks for the feedback, and pointing out the stale example @kaihendry. We can move some of these examples from Go docstrings into an example_test.go file so that they are validated to at least compile when the SDK's CIs are run.

@jasdel: Any chance you could post any examples here?

@skyzyx I have added example (I had to follow strange examples convention):
