Enum gooey::ConstraintLimit

pub enum ConstraintLimit {
    Fill(UPx),
    SizeToFit(UPx),
}

A limit used when measuring a widget.

Variants

Fill(UPx)

The widget is expected to occupy a known size.

SizeToFit(UPx)

The widget is expected to resize itself to fit its contents, trying to stay within the size given.

Implementations

impl ConstraintLimit

pub fn min(self) -> UPx

Returns UPx::ZERO when sizing to fit, otherwise it returns the size being filled.

pub fn max(self) -> UPx

Returns the maximum measurement that will fit the constraint.

pub fn fit_measured<Unit>(self, measured: Unit, scale: Fraction) -> UPx

where Unit: ScreenUnit,

Converts measured to unsigned pixels, and adjusts it according to the constraint’s intentions.

If this constraint is of a known size, it will return the maximum of the measured size and the constraint. If it is of an unknown size, it will return the measured size.

Trait Implementations

impl Clone for ConstraintLimit

fn clone(&self) -> ConstraintLimit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintLimit

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

Formats the value using the given formatter.

impl PartialEq for ConstraintLimit

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Sub<UPx> for ConstraintLimit

type Output = ConstraintLimit

The resulting type after applying the - operator.

fn sub(self, rhs: UPx) -> Self::Output

Performs the - operation.
