Enum Ptr 

pub enum Ptr {
    ExtentEntry(usize),
    ExtentData(usize),
    Block(usize),
}

Pointers to the various levels of CP/M disk structures. These just wrap integers and are supposed to help identify what is being indexed.

Variants

ExtentEntry(usize)

Index to the extent’s metadata, ordering its appearance in the directory

ExtentData(usize)

Index stored with the extent, ordering the logical extents within the file

Block(usize)

Global pointer to one of the data blocks associated with a file extent

Implementations

impl Ptr

pub fn unwrap(&self) -> usize

These pointers are just counts, extract the integer.

Trait Implementations

impl Clone for Ptr

fn clone(&self) -> Ptr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Ord for Ptr

fn cmp(&self, other: &Self) -> 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 Ptr

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

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