[−][src]Trait rect::Rect
Helper methods for computing simple rectangle layout.
Associated Types
type Scalar: Float
The internal scalar type.
Required methods
fn from_x_y_w_h(
_: Self::Scalar,
_: Self::Scalar,
_: Self::Scalar,
_: Self::Scalar
) -> Self
_: Self::Scalar,
_: Self::Scalar,
_: Self::Scalar,
_: Self::Scalar
) -> Self
Creates new rectangle from x, y, w, h.
fn x(&self) -> Self::Scalar
Gets x.
fn y(&self) -> Self::Scalar
Gets y.
fn w(&self) -> Self::Scalar
Gets w.
fn h(&self) -> Self::Scalar
Gets h.
fn set_x(&mut self, val: Self::Scalar)
Sets x.
fn set_y(&mut self, val: Self::Scalar)
Sets y.
fn set_w(&mut self, val: Self::Scalar)
Sets w.
fn set_h(&mut self, val: Self::Scalar)
Sets h.
Provided methods
fn from_u32(rect: [u32; 4]) -> Self
Converts from u32 rectangle.
fn from_i32(rect: [i32; 4]) -> Self
Converts from i32 rectangle.
fn xy(&self) -> (Self::Scalar, Self::Scalar)
Returns x and y.
fn wh(&self) -> (Self::Scalar, Self::Scalar)
Returns w and h.
fn xw(&self) -> (Self::Scalar, Self::Scalar)
Return x and w.
fn yh(&self) -> (Self::Scalar, Self::Scalar)
Returns y and h.
fn x1x2(&self) -> (Self::Scalar, Self::Scalar)
Returns left and right.
fn y1y2(&self) -> (Self::Scalar, Self::Scalar)
Returns top and bottom.
fn p1p2(&self) -> ([Self::Scalar; 2], [Self::Scalar; 2])
Returns upper left and lower right corner.
fn xywh(&self) -> (Self::Scalar, Self::Scalar, Self::Scalar, Self::Scalar)
Returns x, y, w, h.
fn center(&self) -> [Self::Scalar; 2]
Returns the center of the rectangle.
fn is_empty(&self) -> bool
Returns true if the rectangle is empty.
fn margin(&self, val: Self::Scalar) -> Self
Computes a margin rectangle. If the margin is too large, an empty rectangle in the middle is returned.
fn split_left(&self, val: Self::Scalar, factor: Self::Scalar) -> (Self, Self)
Splits from the left side of rectangle up to a factor.
fn split_right(&self, val: Self::Scalar, factor: Self::Scalar) -> (Self, Self)
Splits from the right side of rectangle.
fn split_top(&self, val: Self::Scalar, factor: Self::Scalar) -> (Self, Self)
Splits from the top side of rectangle.
fn split_bottom(&self, val: Self::Scalar, factor: Self::Scalar) -> (Self, Self)
Splits from the bottom side of the rectangle.
