Implementations§

Source§

impl Color

Source

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

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

Source

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.
