SFTP Resume Download

See more SFTP Examples

Demonstrates how to resume an SFTP download from a previous partial download. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let sftp = chilkat::SFtp::new();

// Set some timeouts, in milliseconds:
sftp.set_connect_timeout_ms(5000);
sftp.set_idle_timeout_ms(10000);

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
let hostname = "sftp.example.com".to_string();
let port = 22;
if sftp.connect(&hostname, port).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
if sftp.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// After authenticating, the SFTP subsystem must be initialized:
if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Download the file:
let local_file_path = "c:/temp/hamlet.xml".to_string();
let remote_file_path = "subdir1/subdir2/hamlet.xml".to_string();
// The ResumeDownloadFileByName method will check
// the local file and begin downloading the remote file
// at the appropriate point.  For example, if the local
// file is already 215624 bytes long, it will begin downloading
// the remote file at the 215625'th byte -- appending to
// the local file.
if sftp.resume_download_file_by_name(&remote_file_path, &local_file_path).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("Success.");
