Extract PKZIP from HTTP

Extract only the files you need from a zip using HTTP range requests.

The library is very minimal and may not support all types of zip formats.

Uses ureq and is blocking. For the async counterpart see ziponline (ziponline is not a drop-in replacement, it has a similar but different api).

Limitations

Currently only supports DEFLATE decompression and only supports EOCD headers that are less than 256 bytes in size.

Examples

let mut reader = ziponhttp::extract_file(
    agent,         // ureq::Agent
    url,           // url to zip file
    filesize,      // size of zip file (can be set to None).
    "filename.txt" // file to extract
)?;

io::copy(&mut reader, ...);

let zipfile = ziponhttp::ZipReader::get(
    agent,         // ureq::Agent
    url,           // url to zip file
    filesize,      // size of zip file (can be set to None).
)?;

for file in zipfile {
    let file = file?;
    if file.filename.ends_with(".txt") {
        let rdr = ziponhttp::read_file(agent, url, &file)?;
        let content = io::read_to_string(rdr)?;
        println!("The text file says: {content}");
    }
}
