//! Connection mode definitions for FastCGI clients.
//!
//! This module defines the different connection modes that can be used
//! with the FastCGI client: short connection and keep-alive modes.

/// Trait defining the behavior of different connection modes.
pub trait Mode {
    /// Returns whether this mode supports keep-alive connections.
    fn is_keep_alive() -> bool;
}

/// Short connection mode.
///
/// In this mode, the client establishes a new connection for each request
/// and closes it after receiving the response.
pub struct ShortConn;

impl Mode for ShortConn {
    fn is_keep_alive() -> bool {

/// Keep alive connection mode.
///
/// In this mode, the client maintains a persistent connection
/// and can send multiple requests over the same connection.
