Formats the value using the given formatter.

impl Default for RGBA

fn default() -> RGBA

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RGBA

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RGBA

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

Formats the value using the given formatter.

impl From<[u8; 3]> for RGBA

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

Converts to this type from the input type.

impl From<[u8; 4]> for RGBA

fn from(rgba: [u8; 4]) -> Self

Converts to this type from the input type.

impl From<LinColor> for RGBA

fn from(lin: LinColor) -> Self

Converts to this type from the input type.

impl From<RGBA> for LinColor

fn from(color: RGBA) -> Self

Converts to this type from the input type.

impl FromStr for RGBA

type Err = ColorError

The associated error which can be returned from parsing.

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

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

impl Hash for RGBA

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,

impl Ord for RGBA

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

impl PartialEq for RGBA

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

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.
