Struct druid::RoundedRectRadii

pub struct RoundedRectRadii {
    pub top_left: f64,
    pub top_right: f64,
    pub bottom_right: f64,
    pub bottom_left: f64,
}

Radii for each corner of a rounded rectangle.

The use of top as in top_left assumes a y-down coordinate space. Piet (and Druid by extension) uses a y-down coordinate space, but Kurbo also supports a y-up coordinate space, in which case top_left would actually refer to the bottom-left corner, and vice versa. Top may not always actually be the top, but top corners will always have a smaller y-value than bottom corners.

Fields

top_left: f64

The radius of the top-left corner.

top_right: f64

The radius of the top-right corner.

bottom_right: f64

The radius of the bottom-right corner.

bottom_left: f64

The radius of the bottom-left corner.

Implementations

impl RoundedRectRadii

pub const fn new( top_left: f64, top_right: f64, bottom_right: f64, bottom_left: f64 ) -> RoundedRectRadii

Create a new RoundedRectRadii. This function takes radius values for the four corners. The argument order is “top_left, top_right, bottom_right, bottom_left”, or clockwise starting from top_left.

pub const fn from_single_radius(radius: f64) -> RoundedRectRadii

Create a new RoundedRectRadii from a single radius. The radius argument will be set as the radius for all four corners.

pub fn abs(&self) -> RoundedRectRadii

Takes the absolute value of all corner radii.

pub fn clamp(&self, max: f64) -> RoundedRectRadii

For each corner, takes the min of that corner’s radius and max.

pub fn is_finite(&self) -> bool

Returns true if all radius values are finite.

pub fn is_nan(&self) -> bool

Returns true if any corner radius value is NaN.

pub fn as_single_radius(&self) -> Option<f64>

If all radii are equal, returns the value of the radii. Otherwise, returns None.

Trait Implementations

impl Clone for RoundedRectRadii

fn clone(&self) -> RoundedRectRadii

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Data for RoundedRectRadii

fn same(&self, other: &Self) -> bool

Determine whether two values are the same.

impl Debug for RoundedRectRadii

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

Formats the value using the given formatter.

impl Default for RoundedRectRadii

fn default() -> RoundedRectRadii

Returns the “default value” for a type.

impl From<(f64, f64, f64, f64)> for RoundedRectRadii

fn from(radii: (f64, f64, f64, f64)) -> RoundedRectRadii

Converts to this type from the input type.

impl From<RoundedRectRadii> for Value

fn from(val: RoundedRectRadii) -> Value

Converts to this type from the input type.

impl From<f64> for RoundedRectRadii

fn from(radius: f64) -> RoundedRectRadii

Converts to this type from the input type.

impl Mul<RoundedRectRadii> for TranslateScale

type Output = RoundedRectRadii

The resulting type after applying the * operator.

fn mul(self, other: RoundedRectRadii) -> RoundedRectRadii

Performs the * operation.

impl PartialEq<RoundedRectRadii> for RoundedRectRadii

fn eq(&self, other: &RoundedRectRadii) -> 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 ValueType for RoundedRectRadii

fn try_from_value(value: &Value) -> Result<Self, ValueTypeError>

Attempt to convert the generic Value into this type.
