mμnzip

mμnzip is a port of JUnzip to Rust.

mμnzip exclusively supports STORE and DEFLATE. Support for ZLIB was intentionally omitted.

features

iterable

let zi = munzip::IterableArchive::new(&mut input).unwrap();

for entry in zi {
    let mut entry = entry.unwrap();
    let filename = entry.filename();
    let buffer = entry.buffer().unwrap();
    write::write_file(&filename, &buffer).unwrap();
}

searchable

let mut zi = munzip::SearchableArchive::new(&mut input).unwrap();

let filename = "munzip/Cargo.toml";
let cargo_toml = zi.by_name(filename).unwrap().unwrap();
write::write_file(&"Cargo.toml".to_owned(), &cargo_toml).unwrap();

why?

• To be small.
• To have a simple unzip library with minimal (2)(inflate,adler32) dependencies.
• For fun and practice.

CONCLUSIONS:

• is it very fast? no
• is it very small? no
• very featureful? no

😐👍

NOTES:

• 'zip' refers to the zip crate
• 'zip' was set to default-features = false, features = ["deflate"]
• 'unzip' refers to debian's unzip package
• 'unzip' size includes libc and libbz2
• all binaries are stripped
• Speed was measured by unzipping an archive of this entire repository on my laptop, so.
