1//! Error types for the r-token authentication library.

7/// Errors that can occur during token management operations.
8///
9/// This error type implements `std::error::Error` and `actix_web::ResponseError`,
10/// allowing it to be used seamlessly in actix-web handlers.
11///
12/// # Examples
13///
14/// ```rust
15/// use r_token::{RTokenManager, RTokenError};
16///
17/// let manager = RTokenManager::new();
18/// let result = manager.login("user123");
19///
20/// match result {
21///     Ok(token) => println!("Token generated: {}", token),
22///     Err(RTokenError::MutexPoisoned) => eprintln!("Failed to acquire lock"),
23/// }
24/// ```
