Rust Requires Chilkat v11.0.0+

Find a ZIP Entry by Exact Path Using EntryOf

See more Zip Examples

This example demonstrates how to use the EntryOf method to find a ZIP entry whose stored path exactly matches a specified path.

Unlike EntryMatching, which performs wildcard matching, EntryOf performs an exact path lookup.

This method is useful when:

• The exact ZIP path is already known
• Retrieving a specific file or directory entry
• Verifying whether a particular entry exists in the ZIP archive

Suppose the ZIP archive contains:

docs/
docs/readme.txt
docs/manual.pdf
images/logo.png
data/config/settings.json

ZIP archives may optionally contain explicit directory entries such as docs/. These directory entries can also be retrieved using EntryOf.

The example:

• Finds an exact file entry
• Finds an exact directory entry
• Demonstrates the difference between file and directory entries

Rust

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

let _ = false;

// Open an existing ZIP archive.
let zip = chilkat::Zip::new();

if zip.open_zip("example.zip").is_err() {
    println!("{}", zip.last_error_text());
    return;
}

let entry = chilkat::ZipEntry::new();

// ------------------------------------------------------------
// Find a specific file entry by its exact ZIP path.

if zip.entry_of("docs/readme.txt", &entry).is_ok() {
    println!("Found file entry:");
    println!("  FileName = {}", entry.file_name());
    println!("  IsDirectory = {}", entry.is_directory());
    println!("");
}

// ------------------------------------------------------------
// Find a directory entry.
// 
// ZIP archives may optionally contain explicit directory entries.
// In this example, "docs/" is a separate directory entry.

if zip.entry_of("docs/", &entry).is_ok() {
    println!("Found directory entry:");
    println!("  FileName = {}", entry.file_name());
    println!("  IsDirectory = {}", entry.is_directory());
    println!("");
}

// ------------------------------------------------------------
// Attempt to find a non-existent entry.

if zip.entry_of("images/missing.png", &entry).is_err() {
    println!("The entry images/missing.png was not found.");
}

zip.close_zip();

println!("Done.");
