Compress Text from StringBuilder to Gzip (BinData Output)

See more Gzip Examples

This example demonstrates how to use the CompressSb method to compress text stored in a StringBuilder into Gzip format.

The text is first converted to its byte representation using the specified character set (in this case, UTF-8). These bytes are then compressed, and the resulting Gzip data is written to a BinData object in memory.

This approach is useful when working with dynamically generated text that you want to compress without first writing it to a file. The example also shows how the compressed data can optionally be saved to a .gz file.

Rust

// This example demonstrates how to compress text contained in a StringBuilder
// into Gzip format, storing the compressed result in a BinData object.

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

// Add some text to the StringBuilder:
let _ = sb.append("The quick brown fox jumps over the lazy dog.");

// Compress the text using UTF-8 encoding:
if gzip.compress_sb(&sb, "utf-8", &bd).is_err() {
    println!("{}", gzip.last_error_text());
    return;
}

// The BinData now contains the Gzip-compressed bytes.
println!("Compression successful.");
println!("Compressed size (bytes): {}", bd.num_bytes());

// (Optional) Save to a .gz file:
if bd.write_file("text.gz").is_err() {
    println!("{}", bd.last_error_text());
    return;
}

println!("Gzip file written to text.gz");
