better-auth 0.10.0

//! # Better Auth - Rust
//!
//! A comprehensive authentication framework for Rust, inspired by Better-Auth.
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use better_auth::{AuthBuilder, AuthConfig};
//! use better_auth::adapters::MemoryDatabaseAdapter;
//! use better_auth::plugins::EmailPasswordPlugin;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     let config = AuthConfig::new("your-secret-key-that-is-at-least-32-chars");
//!
//!     let auth = AuthBuilder::new(config)
//!         .database(MemoryDatabaseAdapter::new())
//!         .plugin(EmailPasswordPlugin::new())
//!         .build()
//!         .await?;
//!
//!     Ok(())
//! }
//! ```
