Struct BorderRect 

pub struct BorderRect {
    pub min_inset: Vec2,
    pub max_inset: Vec2,
}

Defines border insets that shrink a rectangle from its minimum and maximum corners.

This struct is used to represent thickness or offsets from the four edges of a rectangle, with values increasing inwards.

Fields

min_inset: Vec2

Inset applied to the rectangle’s minimum corner

max_inset: Vec2

Inset applied to the rectangle’s maximum corner

Implementations

impl BorderRect

pub const ZERO: BorderRect

An empty border with zero thickness along each edge

pub const fn all(inset: f32) -> BorderRect

Creates a border with the same inset along each edge
