Struct embedded_graphics::pixelcolor::Rgb565

pub struct Rgb565(pub u16);

A pixel type defining the commonly used RGB565 format

Pixel values are stored in a single u16 segmented as follows:

15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0
 r  r  r  r  r  g  g  g  g  g  g  b  b  b  b  b

Methods

impl Rgb565

pub fn r(&self) -> u8

Get the red component as a u8

The least significant 3 bits will always be 0

pub fn g(&self) -> u8

Get the green component as a u8

The least significant 2 bits will always be 0

pub fn b(&self) -> u8

Get the blue component as a u8

The least significant 3 bits will always be 0

Trait Implementations

impl Clone for Rgb565

fn clone(&self) -> Rgb565

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Rgb565

impl Debug for Rgb565

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

Formats the value using the given formatter.

impl From<[u8; 2]> for Rgb565

Build a u16 from two u8s

Uses u16::from_be_bytes internally. If the input bytes are little endian, use u16::from_le_bytes directly:

use embedded_graphics::pixelcolor::Rgb565;

let pixel = Rgb565(u16::from_le_bytes([0xab, 0xcd]));

assert_eq!(pixel, Rgb565(0xCDAB));

fn from(other: [u8; 2]) -> Self

Performs the conversion.

impl From<(u8, u8, u8)> for Rgb565

Take a tuple of 8 bit (red, green, blue) color values and convert them to a single 16 bit color

The 2 or 3 (for the green channel) least significant bits are discarded

fn from((r, g, b): (u8, u8, u8)) -> Self

Performs the conversion.

impl From<u16> for Rgb565

fn from(other: u16) -> Self

Performs the conversion.

impl From<u8> for Rgb565

Convert from an 8 bit greyscale colour into a 16 bit greyscale representation

The 5 (or 6 for the green channel) most significant bits are taken from the input and assigned to the three colour channels see http://www.barth-dev.de/online/rgb565-color-picker/ for a more in depth explanation.

fn from(other: u8) -> Self

Performs the conversion.

impl PartialEq<Rgb565> for Rgb565

fn eq(&self, other: &Rgb565) -> bool

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

fn ne(&self, other: &Rgb565) -> bool

This method tests for !=.
