Struct Constraints 

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

The size range a parent offers a child: every laid-out size must satisfy min <= size <= max component-wise.

Fields

min: Size

max: Size

Implementations

impl Constraints

pub fn loose(max: Size) -> Self

Loose constraints: anything from zero up to max.

pub fn tight(size: Size) -> Self

Tight constraints: exactly size.

pub fn constrain(&self, size: Size) -> Size

Clamp size into the allowed range.

pub fn deflate(&self, horizontal: f64, vertical: f64) -> Self

Shrink the available maximum by amount on each side’s total (e.g. for padding), keeping min no larger than the new max.

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 Copy for Constraints

impl Debug for Constraints

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

Formats the value using the given formatter.

impl PartialEq for Constraints

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