Implementations

impl<T, U> BorderRadius<T, U>

pub const fn new( top_left: T, top_right: T, bottom_right: T, bottom_left: T, ) -> Self

Constructor taking a scalar for each radius.

Radii are specified in top-left, top-right, bottom-right, bottom-left order following CSS’s convention.

pub fn from_lengths( top_left: Length<T, U>, top_right: Length<T, U>, bottom_right: Length<T, U>, bottom_left: Length<T, U>, ) -> Self

Constructor taking a typed Length for each radius.

Radii are specified in top-left, top-right, bottom-right, bottom-left order following CSS’s convention.

pub fn new_uniform(all: T) -> Self

where T: Copy,

Constructor taking the same scalar value for all radii.

pub fn from_length(all: Length<T, U>) -> Self

where T: Copy,

Constructor taking the same typed Length for all radii.

pub fn is_uniform(&self) -> bool

where T: ApproxEq<T>,

Returns true if all radii are equal.

pub fn as_uniform(&self) -> Option<T>

where T: Copy + ApproxEq<T>,

Returns the uniform radius if all are equal, or None otherwise.

pub fn is_zero(&self) -> bool

where T: ApproxEq<T> + Zero,

Returns true if all radii are zero.

pub fn outer(&self, half_border_width: Length<T, U>) -> Self

where T: Copy + PartialOrd + Zero,

Returns the outer radius.

For any corner with a positive radius, the radius is ensured to be at least half_border_width.

pub fn inner(&self, half_border_width: Length<T, U>) -> Self

where T: Copy + PartialOrd + Sub<T, Output = T> + Zero,

Returns the inner radius.

A positive radius of each corner is subtracted by half_border_width and min-clamped to zero.

impl<T, U> BorderRadius<T, U>

where T: PartialOrd,

pub fn min(self, other: Self) -> Self

Returns the minimum of the two radii.

pub fn max(self, other: Self) -> Self

Returns the maximum of the two radii.

impl<T, U> BorderRadius<T, U>

where T: NumCast + Copy,

pub fn cast<NewT: NumCast>(self) -> BorderRadius<NewT, U>

Cast from one numeric representation to another, preserving the units.

pub fn try_cast<NewT: NumCast>(self) -> Option<BorderRadius<NewT, U>>

Fallible cast from one numeric representation to another, preserving the units.
