Struct UnpackOptions 

pub struct UnpackOptions {
    pub threads: usize,
    pub parallel_gzip: bool,
    pub same_owner: bool,
    pub layout: Layout,
    pub devices: Devices,
}

How to unpack layers.

Fields

threads: usize

Threads for file writes and parallel gzip decode; 0 means all cores this process may use. 1 unpacks on the calling thread only.

parallel_gzip: bool

Decode gzip layers with lgz on threads workers (false: one-core zlib-rs).

same_owner: bool

Restore the uid/gid of every entry (needs root or CAP_CHOWN).

layout: Layout

Apply whiteouts onto rootfs (flatten), or keep them in overlayfs form for a per-layer directory.

devices: Devices

What to do with a layer’s character and block devices (fifos are always made). Default Devices::Skip.
