#[repr(transparent)]pub struct Color { /* private fields */ }
Expand description
The Color
structure is used to
represent a color in an uncalibrated RGB color-space.
Implementations§
source§impl Color
impl Color
sourcepub fn parse(spec: &str) -> Result<Self, BoolError>
pub fn parse(spec: &str) -> Result<Self, BoolError>
Fill in the fields of a color from a string specification.
The string can either one of a large set of standard names.
(Taken from the CSS Color specification,
or it can be a value in the form #rgb
, #rrggbb
,
#rrrgggbbb
or #rrrrggggbbbb
, where r
, g
and b
are hex digits of the red, green, and blue components
of the color, respectively. (White in the four forms is
#fff
, #ffffff
, #fffffffff
and #ffffffffffff
.)
spec
a string specifying the new color
Returns
sourcepub fn parse_with_alpha(spec: &str) -> Result<(Self, u16), BoolError>
Available on crate feature v1_46
only.
pub fn parse_with_alpha(spec: &str) -> Result<(Self, u16), BoolError>
v1_46
only.Fill in the fields of a color from a string specification.
The string can either one of a large set of standard names.
(Taken from the CSS Color specification,
or it can be a hexadecimal value in the form #rgb
,
#rrggbb
, #rrrgggbbb
or #rrrrggggbbbb
where r
, g
and b
are hex digits of the red, green, and blue components
of the color, respectively. (White in the four forms is
#fff
, #ffffff
, #fffffffff
and #ffffffffffff
.)
Additionally, parse strings of the form #rgba
, #rrggbbaa
,
#rrrrggggbbbbaaaa
, if @alpha is not None
, and set @alpha
to the value specified by the hex digits for a
. If no alpha
component is found in @spec, @alpha is set to 0xffff (for a
solid color).
spec
a string specifying the new color
Returns
true
if parsing of the specifier succeeded,
otherwise false
alpha
return location for alpha
