Enum PopupConstraint

#[non_exhaustive]
pub enum PopupConstraint {
    None,
    Above(Alignment, Rect),
    Below(Alignment, Rect),
    Left(Alignment, Rect),
    Right(Alignment, Rect),
    AboveOrBelow(Alignment, Rect),
    BelowOrAbove(Alignment, Rect),
    Position(u16, u16),
}

Placement relative to the widget area + the widget area.

The render() call for PopupCore will only use the size of the area given to the render call as the size of the popup. It will calculate the position of the popup given one of these constraints.

If you build a widget that uses a PopupCore internally you will rather use Placement as a parameter

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

Use the render-area for the popup as is.

Above(Alignment, Rect)

Synonym for AboveLeft

Below(Alignment, Rect)

Synonym for BelowLeft

Left(Alignment, Rect)

Synonym for LeftTop

Right(Alignment, Rect)

Synonym for RightTop

AboveOrBelow(Alignment, Rect)

Above or below dependent on available space. Aligned left.

BelowOrAbove(Alignment, Rect)

Below or above dependent on available space. Aligned left.

Position(u16, u16)

Use the render-area for the popup, but place it at position (x,y).

Trait Implementations

impl Clone for PopupConstraint

fn clone(&self) -> PopupConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PopupConstraint

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

Formats the value using the given formatter.

impl Default for PopupConstraint

fn default() -> PopupConstraint

Returns the “default value” for a type.

impl PartialEq for PopupConstraint

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