Rust

Disconnect from an SFTP Server

Demonstrates the Chilkat SFtp.Disconnect method, which closes the current SSH/SFTP connection. It takes no arguments. All remote file and directory handles from the session become invalid and must not be reused.

Background: Disconnecting releases the SSH transport and every SFTP handle opened on it. The object itself stays reusable, but a later session must repeat the full setup — Connect, authenticate, then InitializeSftp — because the SFTP subsystem does not survive a disconnect.

// Step 1: Connect the SSH transport.  Port 22 is the usual port.
let port = 22;

// from an interactive prompt, environment variable, or a secrets vault.
let password = "mySshPassword".to_string();

    println!("{}", sftp.last_error_text());
    return;

// Step 3: Open the SFTP subsystem.  This must be done after authentication and before any
// file or directory operations.
if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// ... perform SFTP operations ...

// Close the connection.  The object remains reusable: a later session must Connect,
// authenticate, and InitializeSftp again.
sftp.disconnect();
