ullun-api 0.4.6

//! File drive: upload, store, share and download files
//!
//! Multipart uploads with per-user quotas, files stored on disk under generated
//! names (never the client's), downloads with resumable ranges, time- and
//! count-limited share links, safe handling of risky file types, a background
//! cleanup task and an OpenAPI document.
//!
//! Configuration (environment):
//!   PORT         listen port (default 3000)
//!   DATA_DIR     where blobs and the index live (default ./drive-data)
//!   DRIVE_USERS  `name:api-key:quota-mb,...` (required unless DEV=1)
//!   DEV          1 = demo users alice/bob with demo keys
//!
//! Run:   DEV=1 cargo run --example drive
//! Try:   curl -s -H 'x-api-key: alice-demo-key-0123456789' -F file=@README.md -F description=docs \
//!             localhost:3000/api/upload
//!        curl -s -H 'x-api-key: alice-demo-key-0123456789' -X POST localhost:3000/api/files/<id>/share \
