Enum SizeConstraint

pub(crate) enum SizeConstraint {
    Definite(Au),
    MinMax(Au, Option<Au>),
}

Represents the sizing constraint that the preferred, min and max sizing properties impose on one axis.

Variants

Definite(Au)

Represents a definite preferred size, clamped by minimum and maximum sizes (if any).

MinMax(Au, Option<Au>)

Represents an indefinite preferred size that allows a range of values between the first argument (minimum size) and the second one (maximum size).

Implementations

impl SizeConstraint

pub(crate) fn new( preferred_size: Option<Au>, min_size: Au, max_size: Option<Au>, ) -> Self

pub(crate) fn is_definite(self) -> bool

pub(crate) fn to_definite(self) -> Option<Au>

Trait Implementations

impl Clone for SizeConstraint

fn clone(&self) -> SizeConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SizeConstraint

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

Formats the value using the given formatter.

impl Default for SizeConstraint

fn default() -> Self

Returns the “default value” for a type.

impl From<Option<Au>> for SizeConstraint

fn from(size: Option<Au>) -> Self

Converts to this type from the input type.

impl MallocSizeOf for SizeConstraint

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for SizeConstraint

fn eq(&self, other: &SizeConstraint) -> 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 SizeConstraint
