Struct Constraints 

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

Box layout constraints: a [min, max] range for width and height.

Fields

min: Size

Minimum allowed size.

max: Size

Maximum allowed size (use f32::INFINITY for unbounded).

Implementations

impl Constraints

pub const fn new(min: Size, max: Size) -> Self

Construct constraints from a min and max size.

pub fn tight(size: Size) -> Self

Tight constraints that force exactly size.

pub fn loose(max: Size) -> Self

Loose constraints: min is zero, max is the given size.

pub fn unbounded() -> Self

Unbounded constraints (zero min, infinite max).

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

Clamp size into this constraint range.

pub fn is_tight(&self) -> bool

Returns true if only one size satisfies both width and height bounds.

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.

impl Default for Constraints

fn default() -> Self

Returns the “default value” for a type.

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.

impl Copy for Constraints
