Struct Constraints

pub struct Constraints {
    pub min: Vec2,
    pub max: Vec2,
}

Defines box constraints used for layout.

Fields

min: Vec2

The minimum size that is allowed by these constraints.

max: Vec2

The maximum size that is allowed by these constraints.

Implementations

impl Constraints

pub fn loose(max: Vec2) -> Self

Create a new Constraints with a minimum size of zero and the given maximum.

pub fn tight(value: Vec2) -> Self

Create a new Constraints whose minimum and maximum constraints are the given value.

pub fn none() -> Self

Create a new Constraints whose minimum size is zero and whose maximum is infinite.

pub fn constrain_min(&self, base: Vec2) -> Vec2

Returns the size closest to the given size that satisfies the minimun constraints.

pub fn constrain(&self, base: Vec2) -> Vec2

Returns the size closest to the given size that fits the constraints.

pub fn constrain_width(&self, width: f32) -> f32

Returns the width closest to the given width that fits the constraints.

pub fn constrain_height(&self, height: f32) -> f32

Returns the height closest to the given height that fits the constraints.

pub fn is_loose(&self) -> bool

Constraints are loose if there is no minimum size.

pub fn is_tight(&self) -> bool

Constraints are tight if the minimum size and maximum size are the same. This means that there is exactly only size that satisfies the constraints.

pub fn is_bounded(&self) -> bool

Constraints are bounded if the maximum size on both axes is finite.

pub fn is_unbounded(&self) -> bool

Constraints are unbounded if the maximum size on either axis is infinite.

Trait Implementations

impl Clone for Constraints

fn clone(&self) -> Constraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraints

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

Formats the value using the given formatter.
