Struct mooeye::ui::Visuals

pub struct Visuals {
    pub background: Color,
    pub border: Color,
    pub border_widths: [f32; 4],
    pub corner_radii: [f32; 4],
}

A struct that describes the additional visual elements of the background added to an element. This background will be drawn first and also contain the padding if any.

Fields

background: Color

The color of the background.

border: Color

The color of the border, if present.

border_widths: [f32; 4]

The width of the borders. Layout:

        0
    +------+
  3 |      | 1
    +------+
        2

corner_radii: [f32; 4]

The radius of the corners. Layout:

   3        0

Trait Implementations

impl Clone for Visuals

fn clone(&self) -> Visuals

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Visuals

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

Formats the value using the given formatter.

impl Default for Visuals

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Visuals> for Visuals

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Visuals

impl StructuralPartialEq for Visuals
