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 constraint for PopupCore.

This defines a position relative to the main widget, plus an alignment and the main widget area.

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)

Place above the main widget area.

Below(Alignment, Rect)

Place below the main widget area.

Left(Alignment, Rect)

Place left of the main widget area. Alignment::Left == Top, Alignment::Center == Middle, Alignment::Right == Bottom

Right(Alignment, Rect)

Place right of the main widget area. Alignment::Left == Top, Alignment::Center == Middle, Alignment::Right == Bottom

AboveOrBelow(Alignment, Rect)

Above or below the main widget dependent on available space.

BelowOrAbove(Alignment, Rect)

Below or above the main widget dependent on available space.

Position(u16, u16)

Place the popup at this position.

Trait Implementations

impl Clone for PopupConstraint

fn clone(&self) -> PopupConstraint

Returns a duplicate 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.
