Crate rustack_s3_core 

S3 service implementation for Rustack.

This crate implements the S3 business logic provider (RustackS3) that can be plugged into the rustack-s3-http service layer via the S3Handler trait. It supports bucket CRUD, object CRUD, multipart uploads, versioning, CORS, tagging, ACLs, encryption metadata, checksums, object lock, and more.
