Reading an archive

use libpna::{Archive, ReadOptions};
use std::fs::File;
use std::io::{self, copy, prelude::*};

fn main() -> io::Result<()> {
    let file = File::open("foo.pna")?;
    let mut archive = Archive::read_header(file)?;
    for entry in archive.entries_skip_solid() {
        let entry = entry?;
        let mut file = File::create(entry.header().path().as_path())?;
        let mut reader = entry.reader(ReadOptions::builder().build())?;
        copy(&mut reader, &mut file)?;
    }
    Ok(())
}

Writing an archive

use libpna::{Archive, EntryBuilder, WriteOptions};
use std::fs::File;
use std::io::{self, prelude::*};

fn main() -> io::Result<()> {
    let file = File::create("foo.pna")?;
    let mut archive = Archive::write_header(file)?;
    let mut entry_builder = EntryBuilder::new_file(
        "bar.txt".into(),
        WriteOptions::builder().build(),
    )?;
    entry_builder.write(b"content")?;
    let entry = entry_builder.build()?;
    archive.add_entry(entry)?;
    archive.finalize()?;
    Ok(())
