Enum FillPattern 

pub enum FillPattern {
    Zeros,
    Ones,
    Uniform(u8),
    Alternating(u8, u8),
    HighEntropy,
    Mixed,
}

The dominant fill pattern of a byte region.

Variants

Zeros

Entirely 0x00 — ordinary unallocated space (not a deliberate-wipe signal).

Ones

Entirely 0xFF.

Uniform(u8)

Entirely one repeated byte value (other than 0x00 / 0xFF).

Alternating(u8, u8)

A repeating two-byte alternation a, b, a, b, … with a != b.

HighEntropy

Near-maximal Shannon entropy — pseudo-random or encrypted fill.

Mixed

No dominant pattern — ordinary structured data.

Implementations

impl FillPattern

pub fn is_deliberate_wipe(self) -> bool

true when this pattern is the signature of a deliberate overwrite.

All-zero space is excluded: it is the default state of unallocated sectors and carries no destruction signal on its own.

pub fn label(self) -> String

Short human-readable label, e.g. "all 0xFF" or "alternating 0x55/0xAA".

Trait Implementations

impl Clone for FillPattern

fn clone(&self) -> FillPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FillPattern

impl Debug for FillPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for FillPattern

impl PartialEq for FillPattern

fn eq(&self, other: &FillPattern) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
