Struct FileBlockNumber 

#[repr(transparent)]
pub struct FileBlockNumber(pub usize);

Represents a file block number within a file.

This number refers to the position of a block within a specific file. Each block contains 4096 bytes of contents. It helps in translating file-relative offsets to actual storage locations.

Tuple Fields

0: usize

Implementations

impl FileBlockNumber

pub const fn from_offset(offset: usize) -> Self

Computes the file block number from a byte offset within a file.

In KeOS, each file is divided into file blocks of 0x1000 bytes (4 KiB). This function calculates the file block index corresponding to a given byte offset.

Parameters

• offset: The byte offset within the file.

Returns

• The FileBlockNumber that corresponds to the given offset.

Trait Implementations

impl Add<usize> for FileBlockNumber

type Output = FileBlockNumber

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Self

Performs the + operation.

impl Clone for FileBlockNumber

fn clone(&self) -> FileBlockNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileBlockNumber

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

Formats the value using the given formatter.

impl Ord for FileBlockNumber

fn cmp(&self, other: &FileBlockNumber) -> 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 FileBlockNumber

fn eq(&self, other: &FileBlockNumber) -> 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 FileBlockNumber

fn partial_cmp(&self, other: &FileBlockNumber) -> 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.

fn steps_between(start: &Self, end: &Self) -> (usize, Option<usize>)

🔬This is a nightly-only experimental API. (step_trait)

Returns the bounds on the number of successor steps required to get from start to end like [Iterator::size_hint()][Iterator::size_hint()].

fn forward_checked(start: Self, count: usize) -> Option<Self>

🔬This is a nightly-only experimental API. (step_trait)
