Struct kas_core::geom::Quad

#[repr(C)]
pub struct Quad {
    pub a: Vec2,
    pub b: Vec2,
}

Axis-aligned 2D cuboid, specified via two corners a and b

Typically it is expected that a.le(b), although this is not required.

Fields

a: Vec2

b: Vec2

Trait Implementations

impl Add<Vec2> for Quad

type Output = Quad

The resulting type after applying the + operator.

fn add(self, rhs: Vec2) -> Self::Output

Performs the + operation.

impl AddAssign<Vec2> for Quad

fn add_assign(&mut self, rhs: Vec2)

Performs the += operation.

impl Clone for Quad

fn clone(&self) -> Quad

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Conv<Rect> for Quad

fn try_conv(rect: Rect) -> Result<Self>

Try converting from T to Self

fn conv(v: T) -> Self

Convert from T to Self

impl Debug for Quad

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

Formats the value using the given formatter.

impl Default for Quad

fn default() -> Quad

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Quad

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<Quad> for Quad

fn eq(&self, other: &Quad) -> 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 Serialize for Quad

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

Serialize this value into the given Serde serializer.

impl Sub<Vec2> for Quad

type Output = Quad

The resulting type after applying the - operator.

fn sub(self, rhs: Vec2) -> Self::Output

Performs the - operation.

impl SubAssign<Vec2> for Quad

fn sub_assign(&mut self, rhs: Vec2)

Performs the -= operation.

impl Copy for Quad

impl StructuralPartialEq for Quad
