Struct usvg::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 black() -> Color

Constructs a new Color set to black.

pub fn white() -> Color

Constructs a new Color set to white.

pub fn gray() -> Color

Constructs a new Color set to gray.

pub fn red() -> Color

Constructs a new Color set to red.

pub fn green() -> Color

Constructs a new Color set to green.

pub fn blue() -> Color

Constructs a new Color set to blue.

Trait Implementations

impl Clone for Color

pub fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Color

impl Debug for Color

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

Formats the value using the given formatter.

impl Display for Color

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

Formats the value using the given formatter.

impl FromStr for Color

type Err = Error

The associated error which can be returned from parsing.

pub fn from_str(text: &str) -> Result<Color, Error>

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> 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.

impl PartialEq<Color> for Color

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralPartialEq for Color

impl WriteBuffer for Color

pub fn write_buf_opt(&self, opt: &WriteOptions, buf: &mut Vec<u8, Global>)

Writes data to the Vec<u8> buffer using specified WriteOptions.

pub fn write_buf(&self, buf: &mut Vec<u8, Global>)

Writes data to the Vec<u8> buffer using default WriteOptions.

pub fn with_write_opt(&'a self, opt: &'a WriteOptions) -> DisplaySvg<'a, Self>

Returns an object that implements fmt::Display using provided write options.
