:warning: **This create is still under heavy development and not yet production ready.**
## What is S4
S4 is attempt to provide a high-level API for S3. It is based on [Rusoto](https://www.rusoto.org/) and merely extents it's API.
## What is added that *Rusoto* itself doesn't provide
* simple way to create an `S3Client`
* download object to a file
* download object and [`Write`] it
* upload object from file
* [`Read`] object and upload it
* simple way to iterate through all objects or objects with a given prefix
## Implementation details
Most functionality is provided by the `S4` trait which is implemented for *Rusoto*'s `S3Client`.
