Struct Rect 

pub struct Rect<T> {
    pub left: T,
    pub right: T,
    pub top: T,
    pub bottom: T,
}

An axis-aligned UI rectangle

Fields

left: T

This can represent either the x-coordinate of the starting edge, or the amount of padding on the starting side.

The starting edge is the left edge when working with LTR text, and the right edge when working with RTL text.

right: T

This can represent either the x-coordinate of the ending edge, or the amount of padding on the ending side.

The ending edge is the right edge when working with LTR text, and the left edge when working with RTL text.

top: T

This can represent either the y-coordinate of the top edge, or the amount of padding on the top side.

bottom: T

This can represent either the y-coordinate of the bottom edge, or the amount of padding on the bottom side.
