Struct RawU4

pub struct RawU4(/* private fields */);

4 bits per pixel raw data.

RawU4 is internally stored in an u8. It can be constructed from an u8 by using the new method or by calling RawU4::from(u8_value). To convert a RawU4 back into a u8 the into_inner method can be used.

See the module-level documentation for more information.

Implementations

impl RawU4

pub const fn new(value: u8) -> Self

Creates a new color from the least significant 4 bits of value.

Trait Implementations

impl Clone for RawU4

fn clone(&self) -> RawU4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RawU4

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

Formats the value using the given formatter.

impl Default for RawU4

fn default() -> RawU4

Returns the “default value” for a type.

impl From<Gray4> for RawU4

fn from(color: Gray4) -> Self

Converts to this type from the input type.

impl From<RawU4> for Gray4

fn from(data: RawU4) -> Self

Converts to this type from the input type.

impl From<u8> for RawU4

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for RawU4

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 RawU4

fn cmp(&self, other: &RawU4) -> 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 RawU4

fn eq(&self, other: &RawU4) -> 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 RawU4

fn partial_cmp(&self, other: &RawU4) -> 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.

impl RawData for RawU4

const BITS_PER_PIXEL: usize = 4usize

Bits per pixel.

type Storage = u8

Storage type.

fn into_inner(self) -> Self::Storage

Converts this raw data into the storage type.

fn from_u32(value: u32) -> Self

Converts a u32 into a RawData type.

impl Copy for RawU4

impl Eq for RawU4

impl StructuralPartialEq for RawU4

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
