Struct Rgba 

pub struct Rgba<T>(pub T);

Parses an RGBA Color.

Schema

• Bracketed numbers: [0.3, 0.72, 0.98], [124, 54, 87, 255]
• Repeat syntax: [0.3; 3], [0.7; 4]
• Hex strings: "AABBCC", "AABBCCFF", "#AABBCC", "#AABBCCFF"
• Hex number literals: 0xAABBCC, 0xAABBCCFF
• CSS color names: Red, Blue
• TailwindCSS color names: Red100, Sky400

Conversion

Ints are in 0..=255, floats are in 0.0..=1.0.

When parsing to u8, if any value is a float, the color is considered in range 0.0..=1.0

When parsing to float, if all values are ints and any of them is>= 2, the color is considered to be in range 0.0..=255.0.

Tuple Fields

0: T

Trait Implementations

impl<T: Debug> Debug for Rgba<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Rgba<T>

fn default() -> Rgba<T>

Returns the “default value” for a type.

impl FromMacro for Rgba<[f32; 4]>

fn from_one(tt: TokenTree) -> Result<Self, Error>

This will be called if there is only one item

const PREFER_MANY: bool = false

Hint to All and similar extractors to disable length validation.

fn from_many(tokens: TokenStream) -> Result<Self, Error>

This will be called if there is more than one item.

fn peek(tt: &TokenTree) -> bool

Look ahead and determine parsability.

impl FromMacro for Rgba<[u8; 4]>

fn from_one(tt: TokenTree) -> Result<Self, Error>

This will be called if there is only one item

const PREFER_MANY: bool = false

Hint to All and similar extractors to disable length validation.

fn from_many(tokens: TokenStream) -> Result<Self, Error>

This will be called if there is more than one item.

fn peek(tt: &TokenTree) -> bool

Look ahead and determine parsability.

impl<T: Hash> Hash for Rgba<T>

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<T: PartialEq> PartialEq for Rgba<T>

fn eq(&self, other: &Rgba<T>) -> 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.
