Struct Hexa 

pub struct Hexa<'a>(pub Cow<'a, [u8]>);

Natural number represented in big-endian (possibly with leading zeroes).

This is parsed from and pretty-printed to hexadecimal (including leading zeroes). Leading zeroes are ignored during comparison (the represented natural numbers are compared).

Tuple Fields

0: Cow<'a, [u8]>

Implementations

impl<'a> Hexa<'a>

pub fn reborrow(&self) -> Hexa<'_>

pub fn shrink(&self) -> &[u8]

Strips the leading zeroes.

pub fn extend(&mut self, len: usize)

Extends with leading zeroes.

Methods from Deref<Target = Cow<'a, [u8]>>

pub fn to_mut(&mut self) -> &mut <B as ToOwned>::Owned

Acquires a mutable reference to the owned form of the data.

Clones the data if it is not already owned.

Examples

use std::borrow::Cow;

let mut cow = Cow::Borrowed("foo");
cow.to_mut().make_ascii_uppercase();

assert_eq!(
  cow,
  Cow::Owned(String::from("FOO")) as Cow<'_, str>
);

Trait Implementations

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

Formats the value using the given formatter.

impl<'a> Default for Hexa<'a>

fn default() -> Hexa<'a>

Returns the “default value” for a type.

impl<'a> Deref for Hexa<'a>

type Target = Cow<'a, [u8]>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for Hexa<'a>

Mutably dereferences the value.

impl<'a> Display for Hexa<'a>

Available on crate feature host only.

impl<'a> Eq for Hexa<'a>

impl<'a> FromStr for Hexa<'a>

Available on crate feature host only.

type Err = Error

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<'a> Ord for Hexa<'a>

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<'a> PartialEq for Hexa<'a>

fn eq(&self, other: &Self) -> 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<'a> PartialOrd for Hexa<'a>

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.

type Type<'_a> = Hexa<'_a>

fn encode(&self, writer: &mut Writer<'a>) -> Result<()>

fn decode(reader: &mut Reader<'a>) -> Result<Self>
