Enum MountRangeAllocation 

pub enum MountRangeAllocation {
    PunchHole,
    ZeroRange {
        extend: bool,
    },
    Preallocate {
        keep_size: bool,
    },
}

Exact sparse-allocation operation requested by a native mount.

Variants

Replaces the range with allocated canonical zeros.

Fields

extend: bool

Permit logical growth to the range end.

Preallocate

Allocates only holes while preserving all existing content.

Fields

keep_size: bool

Preserve logical file length.
