Enum Placement 

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

Placement of the popup.

Use this enum for your widgets API.

Then convert the Placement to a PopupConstraint and set the constraint with the PopupCore.

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

Place above the main widget area.

Below

Place below the main widget area.

Left

Place left of the main widget area.

Right

Place right of the main widget area.

AboveOrBelow

Above or below the main widget dependent on available space.

BelowOrAbove

Below or above the main widget dependent on available space.

Position(u16, u16)

Place the popup at this position.

Implementations

impl Placement

pub fn into_constraint( self, alignment: Alignment, relative_to_area: Rect, ) -> PopupConstraint

Convert the placement to a PopupConstraint. Needs an extra alignment and the area of the main widget.

Trait Implementations

impl Clone for Placement

fn clone(&self) -> Placement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Placement

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

Formats the value using the given formatter.

impl Default for Placement

fn default() -> Placement

Returns the “default value” for a type.

impl PartialEq for Placement

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