//! A crate for validate user permissions in `actix-web`.
//!
//! For built-in configure see: [`GrantsMiddleware`].
//!
//! To check user access to specific services, you can use: [`proc-macro`] and [`PermissionGuard`] or manual.
//!
//! The library can also be integrated with third-party solutions (like [`httpauth`]), see [`permissions`] module.
//!
//! You can find more [`examples`] in the git repository.

/// # Examples
/// ```
/// use actix_web::{HttpResponse};
/// use actix_web_grants::proc_macro::{has_permissions, has_roles};
///
/// // User should be ADMIN with OP_GET_SECRET permission
/// #[has_permissions["ROLE_ADMIN", "OP_GET_SECRET"]]
/// async fn macro_secured() -> HttpResponse {
///     HttpResponse::Ok().body("some secured info")
/// }
///
/// // Role - is permission with prefix "ROLE_".
/// // User should be ADMIN and MANAGER
/// #[has_roles["ADMIN", "MANAGER"]]
/// async fn role_macro_secured() -> HttpResponse {
///     HttpResponse::Ok().body("some secured info")
/// }
/// ```
