Struct packed_char::PackedChar

pub struct PackedChar(/* private fields */);

Stores either a char or a U22 in 32 bits of space.

Implementations

impl PackedChar

pub const fn from_char(c: char) -> Self

Creates a new value from the given char.

Examples

let pack = PackedChar::from_char('a');
assert_eq!(pack.contents(), Contents::Char('a'));

pub const fn from_u22(u22: U22) -> Self

Creates a new value from the given u22.

Examples

let u22 = U22::from_u32(42).unwrap();
let pack = PackedChar::from_u22(u22);
assert_eq!(pack.contents(), Contents::U22(u22));

pub fn contents(self) -> Contents

Gets the stored value.

Examples

let pack = PackedChar::try_from(42)?;
assert_eq!(pack.contents(), Contents::U22(U22::from_u32(42)?));

let pack = PackedChar::from('a');
assert_eq!(pack.contents(), Contents::Char('a'));

Trait Implementations

impl Clone for PackedChar

fn clone(&self) -> PackedChar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackedChar

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

Formats the value using the given formatter.

impl Default for PackedChar

fn default() -> PackedChar

Returns the “default value” for a type.

impl From<U22> for PackedChar

fn from(u22: U22) -> Self

Converts to this type from the input type.

impl From<char> for PackedChar

fn from(c: char) -> Self

Converts to this type from the input type.

impl Hash for PackedChar

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 Ord for PackedChar

fn cmp(&self, other: &PackedChar) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PackedChar

fn eq(&self, other: &PackedChar) -> 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.

impl PartialOrd for PackedChar

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

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

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.

impl TryFrom<u32> for PackedChar

type Error = U22FromU32Error

The type returned in the event of a conversion error.

fn try_from(n: u32) -> Result<Self, Self::Error>

Performs the conversion.
