FTP Sync Download Tree w/ Must-Match Directory Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only entering directories matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Rust

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

let ftp = chilkat::Ftp2::new();

ftp.set_hostname("ftp.something.com");
ftp.set_username("my_login");
ftp.set_password("my_password");

// Connect and login to the FTP server.
if ftp.connect().is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// Set the current remote directory to the root of
// the tree to be downloaded.
if ftp.change_remote_dir("/subDir1").is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

// Possible synchronization modes are:
// mode=0: Download all files
// mode=1: Download all files that do not exist on the local filesystem.
// mode=2: Download newer or non-existant files.
// mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
// mode=5: Download only missing files or files with size differences.
// mode=6: Same as mode 5, but also download newer files.

// Imagine our remote directory tree has these files and directories:

// 	accentedLatin1.txt
// 	accentedUtf8.txt
// 	alice.key
// 	anter_cert.pem
// 	chiliPepper.gif
// 	helloWorld.pdf
// 	abc/chiliPepper.gif
// 	abc/ghk/
// 	data/chiliPepper.gif
// 	data/xyz/dkimHtmlBody.txt
// 	data/xyz/dkimVerifyTest.eml
// 	data/xyz/emailForCreateDsn.eml
// 	text/frenchUtf8.txt
// 	text/helloWorld.txt
// 	text/PolishEmailBody.txt
// 	text/something/

// Only enter remote directories named either "data" or matching "x*"
ftp.set_sync_must_match_dir("data; x*");
let mode = 0;
if ftp.sync_local_tree("c:/temp/subDir1", mode).is_err() {
    println!("{}", ftp.last_error_text());
    return;
}

let _ = ftp.disconnect().is_ok();

// Show the files downloaded.
let st = chilkat::StringTable::new();
ftp.get_synced_files(&st);

let num_files = st.count();
let mut i = 0;
while i < num_files {
    println!("{}", st.string_at(i).unwrap_or_default());
    i = i + 1;
}

// Output showing the files downloaded:

// accentedLatin1.txt
// accentedUtf8.txt
// alice.key
// anter_cert.pem
// chiliPepper.gif
// helloWorld.pdf
// data/chiliPepper.gif
// data/xyz/dkimHtmlBody.txt
// data/xyz/dkimVerifyTest.eml
// data/xyz/emailForCreateDsn.eml
