Struct ImageBytes 

pub struct ImageBytes {
    pub metadata: u64,
    pub layers: u64,
    pub extracted: u64,
    pub disk_image: u64,
    pub base_disk: u64,
    pub total: u64,
    pub exclusive: u64,
}

One image’s byte accounting.

total is everything the image references; exclusive is what dropping this image alone would free. They differ exactly when another cached image shares a blob, which is the case the set difference exists for — and reporting only total would promise bytes back that a shared layer keeps.

Fields

metadata: u64

The manifest and config JSON.

layers: u64

The compressed layer tarballs under images/layers/.

extracted: u64

The unpacked layer trees under images/extracted/.

disk_image: u64

The ext4 disk image built from the layer stack, if one has been built.

base_disk: u64

The guest rootfs base built from that disk image, if one has been built.

total: u64

Everything above.

exclusive: u64

What dropping this image alone would actually free — total minus every byte another cached image also references.
