Struct DirSizing 

pub struct DirSizing {
    pub logical: u64,
    pub allocated: u64,
    pub unique: u64,
    pub unknown_files: u64,
    pub unknown_allocated_bytes: u64,
    pub files: u64,
    pub fully_shared_files: u64,
    pub hardlink_pinned_inodes: u64,
    pub hardlink_pinned_bytes: u64,
    pub clones: CloneSketch,
    pub unreadable_dirs: u64,

}

Aggregate over a directory.

Fields

logical: u64

allocated: u64

unique: u64

unknown_files: u64

Files whose physical reclaim could not be measured.

unknown_allocated_bytes: u64

Allocated bytes excluded from unique because sharing is unknown.

files: u64

fully_shared_files: u64

Files whose blocks were reported fully shared.

hardlink_pinned_inodes: u64

Multiply-linked inodes with at least one name outside this tree.

hardlink_pinned_bytes: u64

Otherwise-unique bytes retained by those outside names.

clones: CloneSketch

A sample of the clone groups this directory’s shared files belong to, for identifying which other directories hold the other half.

unreadable_dirs: u64

Directories that could not be read, so their contents are missing from every figure above.

Silently returning a smaller number for an unreadable tree is the worst failure this type can have: “0 bytes” reads as “nothing to reclaim” when the truth is “could not look”.

confidence: Confidence
