actix-web/actix-files/src/lib.rs

//! Static files support for Actix Web.
//!
//! Provides a non-blocking service for serving static files from disk.
//!
//! # Example
//! ```rust
//! use actix_web::App;
//! use actix_files::Files;
//!
//! let app = App::new()
//!     .service(Files::new("/static", "."));
//! ```
//!
//! # Implementation Quirks
//! - If a filename contains non-ascii characters, that file will be served with the `charset=utf-8`
//!   extension on the Content-Type header.
