rustapi-extras 0.1.453

//! # rustapi-extras
//!
//! Optional security and utility features for the RustAPI framework.
//!
//! This crate provides production-ready middleware and utilities that are
//! opt-in via Cargo feature flags to minimize binary size when not needed.
//!
//! ## Features
//!
//! - `jwt` - JWT authentication middleware and `AuthUser<T>` extractor
//! - `cors` - CORS middleware with builder pattern configuration
//! - `rate-limit` - IP-based rate limiting middleware
//! - `csrf` - CSRF protection using Double-Submit Cookie pattern
//! - `config` - Configuration management with `.env` file support
//! - `cookies` - Cookie parsing extractor
//! - `sqlx` - SQLx database error conversion to ApiError
//! - `insight` - Traffic insight middleware for analytics and debugging
//! - `extras` - Meta feature enabling jwt, cors, and rate-limit
//! - `full` - All features enabled
//!
//! ## CSRF Protection Example
//!
//! ```rust,ignore
//! use rustapi_core::RustApi;
//! use rustapi_extras::csrf::{CsrfConfig, CsrfLayer, CsrfToken};
//!
//! let config = CsrfConfig::new()
//!     .cookie_name("csrf_token")
//!     .header_name("X-CSRF-Token");
//!
//! let app = RustApi::new()
//!     .layer(CsrfLayer::new(config));
//! ```
//!
//! ## Example
//!
//! ```toml
//! [dependencies]
//! rustapi-extras = { version = "0.1.300", features = ["jwt", "cors", "csrf"] }
//! ```
