Struct kas_core::geom::Rect

pub struct Rect {
    pub pos: Coord,
    pub size: Size,
}

An axis-aligned rectangular region

The region is defined by a point pos and an extent size, allowing easy translations. It is empty unless size is positive on both axes.

Fields

pos: Coord

size: Size

Implementations

impl Rect

pub const ZERO: Self = _

The empty rect (all fields zero)

pub const fn new(pos: Coord, size: Size) -> Self

Construct from a Coord and Size

pub fn pos2(&self) -> Coord

Get the second point (pos + size)

pub fn contains(&self, c: Coord) -> bool

Check whether the given coordinate is contained within this rect

pub fn intersection(&self, rhs: &Rect) -> Option<Rect>

Calculate the intersection of two rects

pub fn shrink(&self, n: i32) -> Rect

Shrink self in all directions by the given n

pub fn expand(&self, n: i32) -> Rect

Expand self in all directions by the given n

In debug mode this asserts that n is non-negative.

Trait Implementations

impl Add<Offset> for Rect

type Output = Rect

The resulting type after applying the + operator.

fn add(self, offset: Offset) -> Self

Performs the + operation.

impl AddAssign<Offset> for Rect

fn add_assign(&mut self, offset: Offset)

Performs the += operation.

impl Clone for Rect

fn clone(&self) -> Rect

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 Rect

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

Formats the value using the given formatter.

impl Default for Rect

fn default() -> Rect

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Rect

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

Deserialize this value from the given Serde deserializer.

impl Hash for Rect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Rect> for Rect

fn eq(&self, other: &Rect) -> 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 Rect

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

Serialize this value into the given Serde serializer.

impl Sub<Offset> for Rect

type Output = Rect

The resulting type after applying the - operator.

fn sub(self, offset: Offset) -> Self

Performs the - operation.

impl SubAssign<Offset> for Rect

fn sub_assign(&mut self, offset: Offset)

Performs the -= operation.

impl Copy for Rect

impl Eq for Rect

impl StructuralEq for Rect

impl StructuralPartialEq for Rect
