Struct ntfs::types::Lcn

pub struct Lcn(_);

A Logical Cluster Number (LCN).

NTFS divides a filesystem into clusters of a given size (power of two), see Ntfs::cluster_size. The LCN is an absolute cluster index into the filesystem.

Implementations

impl Lcn

pub fn checked_add(&self, vcn: Vcn) -> Option<Lcn>

Performs a checked addition of the given Virtual Cluster Number (VCN), returning a new LCN.

pub fn position(&self, ntfs: &Ntfs) -> Result<NtfsPosition>

Returns the absolute byte position of this LCN within the filesystem.

pub fn value(&self) -> u64

Returns the stored Logical Cluster Number.

Formats the value using the given formatter.

impl Clone for Lcn

fn clone(&self) -> Lcn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lcn

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

Formats the value using the given formatter.

impl Display for Lcn

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

impl From<u64> for Lcn

fn from(original: u64) -> Lcn

Converts to this type from the input type.

impl LowerHex for Lcn

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

impl Ord for Lcn

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Lcn> for Lcn

fn eq(&self, other: &Lcn) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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