Enum Block

pub enum Block {
    Raw(Box<[u8; 4096]>),
    Fill([u8; 4]),
    Skip,
    Crc32(u32),
}

A sparse block and its associated data.

Variants

Raw(Box<[u8; 4096]>)

A raw block holding a byte buffer of length Block::SIZE.

Fill([u8; 4])

A fill block holding a 4-byte fill value.

Skip

A block that signifies a part of the image that can be skipped.

Crc32(u32)

A CRC32 block holding a checksum value.

Implementations

impl Block

pub const SIZE: u32 = 4_096u32

The size of a sparse file block.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl PartialEq for Block

fn eq(&self, other: &Self) -> 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.
