Enum Codec 

pub enum Codec {
    Zstd(Option<Arc<[u8]>>),
    Stipple(&'static Reader<'static>),
}

How a package’s blocks become file content.

Variants

Zstd(Option<Arc<[u8]>>)

A blocks payload: zstd frames, compressed with the package’s dictionary when it has one, or raw bytes when the footer says the payload is stored.

Stipple(&'static Reader<'static>)

A stipplefs image, opened once for the life of the process.
