Struct Block

pub struct Block {
    pub contents: [u8; 512],
}

A standard 512 byte block (also known as a sector).

IBM PC formatted 5.25“ and 3.5“ floppy disks, IDE/SATA Hard Drives up to about 2 TiB, and almost all SD/MMC cards have 512 byte blocks.

This library does not support devices with a block size other than 512 bytes.

Fields

contents: [u8; 512]

The 512 bytes in this block (or sector).

Implementations

impl Block

pub const LEN: usize = 512usize

All our blocks are a fixed length of 512 bytes. We do not support ‘Advanced Format’ Hard Drives with 4 KiB blocks, nor weird old pre-3.5-inch floppy disk formats.

pub const LEN_U32: u32 = 512u32

Sometimes we want LEN as a u32 and the casts don’t look nice.

pub fn new() -> Block

Create a new block full of zeros.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Default for Block

fn default() -> Self

Returns the “default value” for a type.

impl Deref for Block

type Target = [u8; 512]

The resulting type after dereferencing.

fn deref(&self) -> &[u8; 512]

Dereferences the value.

impl DerefMut for Block

fn deref_mut(&mut self) -> &mut [u8; 512]

Mutably dereferences the value.
