Struct BlockIdx

pub struct BlockIdx(pub u32);

Represents the linear numeric address of a block (or sector). The first block on a disk gets BlockIdx(0) (which usually contains the Master Boot Record).

Tuple Fields

0: u32

Implementations

impl BlockIdx

pub fn into_bytes(self) -> u64

Convert a block index into a 64-bit byte offset from the start of the volume. Useful if your underlying block device actually works in bytes, like open("/dev/mmcblk0") does on Linux.

pub fn range(self, num: BlockCount) -> BlockIter

Create an iterator from the current BlockIdx through the given number of blocks.

Trait Implementations

impl Add<BlockCount> for BlockIdx

type Output = BlockIdx

The resulting type after applying the + operator.

fn add(self, rhs: BlockCount) -> BlockIdx

Performs the + operation.

impl AddAssign<BlockCount> for BlockIdx

fn add_assign(&mut self, rhs: BlockCount)

Performs the += operation.

impl Clone for BlockIdx

fn clone(&self) -> BlockIdx

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockIdx

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

Formats the value using the given formatter.

impl Ord for BlockIdx

fn cmp(&self, other: &BlockIdx) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BlockIdx

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

impl PartialOrd for BlockIdx

fn partial_cmp(&self, other: &BlockIdx) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub<BlockCount> for BlockIdx

type Output = BlockIdx

The resulting type after applying the - operator.

fn sub(self, rhs: BlockCount) -> BlockIdx

Performs the - operation.

impl SubAssign<BlockCount> for BlockIdx

fn sub_assign(&mut self, rhs: BlockCount)

Performs the -= operation.

impl Copy for BlockIdx
