Enum WhConstraint 

pub enum WhConstraint {
    Between(f32, f32),
    EqualTo(f32),
    Unconstrained,
}

Variants

Between(f32, f32)

between min, max

EqualTo(f32)

Value needs to be exactly X

Unconstrained

Value can be anything

Implementations

impl WhConstraint

pub fn min_needed_space(&self) -> Option<f32>

Returns the minimum value or 0 on Unconstrained (warning: this might not be what you want)

pub fn max_available_space(&self) -> Option<f32>

Returns the maximum space until the constraint is violated - returns None if the constraint is unbounded

pub fn is_fixed_constraint(&self) -> bool

Returns if this WhConstraint is an EqualTo constraint

pub fn calculate_from_relative_parent(&self, relative_parent_width: f32) -> f32

Trait Implementations

impl Clone for WhConstraint

fn clone(&self) -> WhConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhConstraint

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

Formats the value using the given formatter.

impl Default for WhConstraint

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for WhConstraint

fn eq(&self, other: &WhConstraint) -> 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.

impl Copy for WhConstraint

impl StructuralPartialEq for WhConstraint
