Struct Rgb 

pub struct Rgb {
    pub r: u8,
    pub g: u8,
    pub b: u8,
}

A 24-bit RGB colour. Ordered red, then green, then blue: an order for maps, not a look.

Fields

r: u8

Red channel.

g: u8

Green channel.

b: u8

Blue channel.

Implementations

impl Rgb

pub const fn new(r: u8, g: u8, b: u8) -> Self

Builds a colour from its channels.

pub fn lerp(self, other: Rgb, t: f32) -> Rgb

Linear interpolation from self (t = 0) to other (t = 1). t is clamped to 0..=1; NaN counts as 0.

pub fn scale(self, factor: f32) -> Rgb

Multiplies every channel by factor (e.g. 0.5 dims by half), saturating at 0 and 255. NaN counts as 0.

pub fn dimmed(self) -> Rgb

This color grey and darker (a game’s unit that has acted, painted Paint::Dimmed): DIM_GREY of the way to its own grey, then DIM_DARK as bright. A change of brightness, not of hue.

pub fn to_hex(self) -> String

Lowercase #rrggbb.

Trait Implementations

impl Clone for Rgb

fn clone(&self) -> Rgb

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rgb

impl Debug for Rgb

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

Formats the value using the given formatter.

impl Eq for Rgb

impl From<Rgb> for [u8; 4]

The colour opaque, as an RGBA pixel: what Image::filled takes.

fn from(c: Rgb) -> Self

Converts to this type from the input type.

impl From<[u8; 3]> for Rgb

fn from([r, g, b]: [u8; 3]) -> Self

Converts to this type from the input type.

impl Hash for Rgb

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 Lerp for Rgb

Channel by channel, in integers: what a Tween of a colour goes through. Past its ends each channel stops at 0 and 255. Rgb::lerp is the same in f32.

fn mix(from: Self, to: Self, p: i32) -> Self

The value p (in 1/65536) of the way from from to to.

impl Ord for Rgb

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Rgb

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