//! Encoding and creation for Sasl Authentication requests.
//!
//! ### Example
//! ```rust
//! let mut sasl_authentication_request = protocol::SaslAuthenticationRequest::new(
//!     correlation_id,
//!     auth_bytes
//! );
//! conn.send_request(&sasl_authentication_request).await?;
//! ```
//!
//! ### Protocol Def
//! ```text
//! SaslAuthenticate Request (Version: 1) => auth_bytes
//!   auth_bytes => BYTES
//! ```
//!
//! Note that we are using version 1 of this API
