Enum BgSpec 

pub enum BgSpec {
    Solid(Rgba),
    Linear {
        angle_deg: f32,
        stops: Vec<(f32, Rgba)>,
    },
    Radial {
        radius: f32,
        stops: Vec<(f32, Rgba)>,
    },
    Conic {
        from_deg: f32,
        stops: Vec<(f32, Rgba)>,
    },
    Image(String),
}

Parsed bg= value. Solid colors, gradients, and images share one attribute surface so authors don’t pick between bg= and bg-gradient=.

Variants

Solid(Rgba)

Solid color.

Linear

CSS-style linear gradient.

Fields

angle_deg: f32

Angle in degrees (CSS convention: 0deg = bottom->top, 90 = left->right).

stops: Vec<(f32, Rgba)>

(offset, color) pairs in source order, after parse-time normalization (sorted by offset ascending).

Radial

CSS-style radial gradient centred on the rect.

Fields

radius: f32

Normalized radius 0..=1 of half-min-dim.

stops: Vec<(f32, Rgba)>

(offset, color) pairs ascending offset.

Conic

CSS-style conic (sweep) gradient.

Fields

from_deg: f32

Starting angle in degrees (CSS: 0 = north, 90 = east).

stops: Vec<(f32, Rgba)>

(offset, color) pairs ascending offset.

Image(String)

url("path"): an image painted behind the element’s content, sized by Attributes::bg_fit. The path is as authored; it resolves against the app directory the way an <image src> does.

Trait Implementations

impl Clone for BgSpec

fn clone(&self) -> BgSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BgSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BgSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BgSpec

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

impl Serialize for BgSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<&'a BgSpec> for Fill

A colour or gradient bg is a Fill. An image is not one: it paints through the asset pipeline instead, and the conversion hands back the path it names.

type Error = &'a str

The type returned in the event of a conversion error.

fn try_from(spec: &'a BgSpec) -> Result<Self, Self::Error>

Performs the conversion.
