Struct Constraint

pub struct Constraint { /* private fields */ }

Constraint describes the constraints properties of a box entity.

Implementations

impl Constraint

The Constraint is used to manage the constraint porperties of an entity.

Constraints will provide properties that are used to determine the size requirements of an entity. It will store minimum and maximim values for its height and width, next to the current values.

pub fn create() -> ConstraintBuilder

Returns a constraint builder.

pub fn width(&self) -> f64

Gets width.

pub fn set_width(&mut self, width: f64)

Sets width.

pub fn height(&self) -> f64

Gets height.

pub fn set_height(&mut self, height: f64)

Sets height.

pub fn size(&self) -> (f64, f64)

Gets the size.

pub fn set_size(&mut self, width: f64, height: f64)

Sets the size.

pub fn min_width(&self) -> f64

Gets min_width.

pub fn set_min_width(&mut self, min_width: f64)

Sets min_width and set width to 0.0.

pub fn min_height(&self) -> f64

Gets min_height.

pub fn set_min_height(&mut self, min_height: f64)

Sets min_height and set height to min_height if height < min_height.

pub fn min_size(&self) -> (f64, f64)

Gets the min_size.

pub fn set_min_size(&mut self, min_width: f64, min_height: f64)

Sets the min size.

pub fn max_width(&self) -> f64

Gets max_width.

pub fn set_max_width(&mut self, max_width: f64)

Sets max_width and set width to 0.0.

pub fn max_height(&self) -> f64

Gets max_height.

pub fn set_max_height(&mut self, max_height: f64)

Sets max_height and set height to 0.0.

pub fn max_size(&self) -> (f64, f64)

Gets the max_size.

pub fn set_max_size(&mut self, max_width: f64, max_height: f64)

Sets the max size.

pub fn perform(&self, size: (f64, f64)) -> (f64, f64)

Adjust the given size.

Asures that size will respect the defined box values for min and max constraints. The value will be adapted if outside of a bound.

Trait Implementations

impl Clone for Constraint

fn clone(&self) -> Constraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constraint

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

Formats the value using the given formatter.

impl Default for Constraint

fn default() -> Constraint

Returns the “default value” for a type.

impl From<ConstraintBuilder> for Constraint

fn from(builder: ConstraintBuilder) -> Constraint

Converts to this type from the input type.

impl PartialEq for Constraint

fn eq(&self, other: &Constraint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
