Struct FileSnapshotState 

pub struct FileSnapshotState {
    pub disk_format: SnapshotFormat,
    pub filesystem: String,
    pub virtual_size: u64,
    pub head: DiskLayerId,
    pub layers: Vec<DiskLayer>,
}

Concrete file-backed snapshot state.

Fields

disk_format: SnapshotFormat

Format of the head layer.

filesystem: String

Filesystem inside the virtual disk.

virtual_size: u64

Guest-visible size of the head layer.

head: DiskLayerId

Opaque identity of the head layer.

layers: Vec<DiskLayer>

Complete physical closure, oldest first.

Implementations

impl FileSnapshotState

pub fn head_layer(&self) -> Result<&DiskLayer, SnapshotManifestError>

Return the validated head layer.

pub fn layer_path(&self, layer: &DiskLayer) -> PathBuf

Return a layer’s canonical artifact-relative path.

pub fn state_root(&self) -> Result<Option<String>, SnapshotManifestError>

Return a representation-sensitive state root when every layer records integrity.
