§Anyreader
A library for reading streams of compressed and uncompressed data without knowing the format in advance.
You can use this to recursively read raw data from potentially compressed streams that may contain archives.
§Installation:
cargo add anyreader
§Example:
The code below will read the contents of a tar.gz archive and print the size of each file. Any archives or compressed files within the archive will also be recursively read:
use anyreader::{recursive_read, FileItem};
use std::path::Path;
use std::fs::File;
use std::io::{self, BufReader};
fn main() -> io::Result<()> {
let path = Path::new("tests/data/archive.tar.gz");
let reader = BufReader::new(File::open(&path)?);
recursive_read(path, reader, &mut |mut item: FileItem<_>| {
println!("Found file: {}", item.path.display());
let size = io::copy(&mut item.reader, &mut io::sink())?;
println!("Size: {}", size);
Ok(())
})?;
Ok(())
}§CLI
The anyreader crate also comes with a CLI tool that can be used to read files from the command line. It will
recursively read any archives or compressed files within the input files, and write the decompressed, flattened
contents to the output file in a tar format.
This requires the cli feature: cargo install anyreader -F cli
anyreader tests/data/archive.tar.gz tests/data/archive-2.zip output.tarA simple CLI tool to read files and directories and write them to a tar archive
Usage: anyreader <INPUT>... <OUTPUT>
Arguments:
<INPUT>... Input files to read. Can be raw, compressed or archive files. Use `-` for stdin
<OUTPUT> Output file to write the tar archive to. Use `-` for stdout
