This experimental project intends to offer an ergonomic adapter for building S3-compatible services.
s3s implements Amazon S3 REST API in the form of a generic hyper service. S3-compatible services can focus on the S3 API itself and don't have to care about the HTTP layer.
s3s-aws provides useful types and integration with aws-sdk-s3.
s3s-fs implements the S3 API based on file system, as a sample implementation. It is designed for integration testing, which can be used to mock an S3 client. It also provides a binary for debugging. Play it!
The diagram above shows how s3s works.
s3s converts HTTP requests to operation inputs before calling the user-defined service.
s3s converts operation outputs or errors to HTTP responses after calling the user-defined service.
The data types, serialization and deserialization are generated from the smithy model in aws-sdk-rust repository. We apply manual hacks to fix some problems in smithy server codegen and make s3s ready to use now.
