Struct Extent 

pub struct Extent {
    pub sector: u32,
    pub length: u64,
    /* private fields */
}

A contiguous region on disk, identified by a starting sector and byte length.

Example

use hadris_common::types::extent::Extent;

let extent = Extent::new(100, 4096);
assert_eq!(extent.sector, 100);
assert_eq!(extent.length, 4096);
assert_eq!(extent.sector_count(2048), 2);
assert_eq!(extent.end_sector(2048), 102);
assert!(!extent.is_empty());

Fields

sector: u32

Starting logical sector (LBA).

length: u64

Size in bytes.

Implementations

impl Extent

pub const fn new(sector: u32, length: u64) -> Self

Creates a new extent.

pub const fn end_sector(&self, sector_size: u32) -> u32

Returns the end sector (exclusive) based on the given sector size.

pub const fn sector_count(&self, sector_size: u32) -> u32

Returns the number of sectors this extent spans.

pub const fn overlaps(&self, other: &Extent, sector_size: u32) -> bool

Checks if this extent overlaps with another.

pub const fn is_empty(&self) -> bool

Checks if this extent is empty (zero length).

Trait Implementations

impl Clone for Extent

fn clone(&self) -> Extent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Extent

impl Debug for Extent

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

Formats the value using the given formatter.

impl Default for Extent

fn default() -> Extent

Returns the “default value” for a type.

impl Display for Extent

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

Formats the value using the given formatter.

impl Eq for Extent

impl Hash for Extent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Extent

fn eq(&self, other: &Extent) -> 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 StructuralPartialEq for Extent

impl Zeroable for Extent

fn zeroed() -> Self

Calls zeroed.
