File storage

Corvis does not have a file storage layer with interchangeable drivers (local disk, S3 or other services) behind a single API.

Alternative

What does exist covers the case of saving and serving files on disk:

• Receiving files: FileInterceptor and the other interceptors in corvis::multer accept multipart/form-data. With disk_storage(DiskStorageOptions::new().destination(..).filename(..)) each file is written to disk, and with memory_storage() it stays in memory. For another destination (a bucket, for example), implement the StorageEngine trait (handle_file and remove_file). See File upload and streaming.
• Sending files: StreamableFile::from_path("report.pdf").await? reads the file in chunks and returns it from a handler.
• Serving a folder: corvis::serve_static(root) or ServeStaticModule::for_root(...) (see Static files).
