easy-archive 0.2.4

/// Easy Archive - A cross-platform archive manipulation library
///
/// This library provides a unified interface for working with various archive formats
/// including TAR, ZIP, and their compressed variants (gzip, xz, bzip2, zstd).
///
/// # Features
///
/// The library uses Cargo features to enable/disable format support:
/// - `tar` - Plain TAR format
/// - `tar-gz` - Gzip-compressed TAR
/// - `tar-xz` - XZ-compressed TAR
/// - `tar-bz` - Bzip2-compressed TAR
/// - `tar-zstd` - Zstd-compressed TAR
/// - `zip` - ZIP format
/// - `default` - Enables all formats
///
/// # Example
///
/// ```no_run
/// use easy_archive::{Fmt, File};
///
/// // Decode an archive
/// let data = std::fs::read("archive.tar.gz")?;
/// let files = Fmt::TarGz.decode(data)?;
///
/// // Encode files into an archive
/// let files = vec![
///     File {
///         path: "hello.txt".to_string(),
///         buffer: b"Hello, world!".to_vec(),
///         ..Default::default()
///     }
/// ];
/// let archive = Fmt::Zip.encode(files)?;
/// std::fs::write("output.zip", archive)?;
/// # Ok::<(), Box<dyn std::error::Error>>(())
/// ```
