Decompress Gzip Data In-Place Using BinData

See more Gzip Examples

This example demonstrates how to use the UncompressBd method to decompress Gzip data stored in a BinData object.

The compressed .gz file is first loaded into memory. The UncompressBd method then decompresses the data in-place, meaning the original compressed bytes in the BinData object are replaced with the uncompressed data.

After decompression, the example writes the resulting data to a file. This approach is useful when working entirely in memory before saving or further processing the uncompressed data.

Rust

// This example demonstrates how to decompress Gzip data stored in a BinData object.
// The decompression is done in-place, replacing the compressed data with the original data.

let gzip = chilkat::Gzip::new();
let bd = chilkat::BinData::new();

// Load a .gz file into BinData:
if bd.load_file("example.txt.gz").is_err() {
    println!("{}", bd.last_error_text());
    return;
}

println!("Compressed size (bytes): {}", bd.num_bytes());

// Uncompress the data in-place:
if gzip.uncompress_bd(&bd).is_err() {
    println!("{}", gzip.last_error_text());
    return;
}

println!("Decompressed size (bytes): {}", bd.num_bytes());

// Save the uncompressed data to a file:
if bd.write_file("example.txt").is_err() {
    println!("{}", bd.last_error_text());
    return;
}

println!("File successfully uncompressed to example.txt");
