Struct Color

pub struct Color {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
}

Representation of the <color> type.

Fields

red: u8

green: u8

blue: u8

Implementations

impl Color

pub fn new(red: u8, green: u8, blue: u8) -> Color

Constructs a new Color from red, green and blue values.

pub fn from_span(span: StrSpan<'_>) -> Result<Color, StreamError>

Parses Color from StrSpan.

Parsing is done according to spec:

color    ::= "#" hexdigit hexdigit hexdigit (hexdigit hexdigit hexdigit)?
             | "rgb(" wsp* integer comma integer comma integer wsp* ")"
             | "rgb(" wsp* integer "%" comma integer "%" comma integer "%" wsp* ")"
             | color-keyword
hexdigit ::= [0-9A-Fa-f]
comma    ::= wsp* "," wsp*

* The SVG spec has an error. There should be number, not an integer for percent values (details).

Errors

• Returns error if a color has an invalid format.

• Returns error if color-keyword or rgb prefix are in in the lowercase. It’s not supported.

• Returns error if <color> is followed by <icccolor>. It’s not supported.

Notes

• Any non-hexdigit bytes will be treated as 0.
• Allocates heap memory for case-insensitive named colors comparison.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl FromStr for Color

type Err = StreamError

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<Self, StreamError>

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

impl PartialEq for Color

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