Struct HAnchor 

pub struct HAnchor(/* private fields */);

Horizontal anchor flags — how a widget sizes and positions itself horizontally within the slot assigned by its parent.

Constant	Meaning
ABSOLUTE	No automatic sizing or positioning (manual bounds).
LEFT	Align to the left edge of the slot (respecting margin).
CENTER	Center horizontally in the slot (respecting margin).
RIGHT	Align to the right edge of the slot (respecting margin).
FIT	Width encloses natural content (default).
STRETCH	Fill the slot width (LEFT | RIGHT).
MAX_FIT_OR_STRETCH	Take the larger of Fit or Stretch.
MIN_FIT_OR_STRETCH	Take the smaller of Fit or Stretch.

At most one of LEFT, CENTER, RIGHT may be set for position anchoring; combining LEFT | RIGHT means “stretch”, not “anchor to both edges”.

Implementations

impl HAnchor

pub const ABSOLUTE: Self

pub const LEFT: Self

pub const CENTER: Self

pub const RIGHT: Self

pub const FIT: Self

Width fits natural content size (default).

pub const STRETCH: Self

Fill parent slot width (LEFT | RIGHT).

pub const MAX_FIT_OR_STRETCH: Self

Take the larger of Fit or Stretch.

pub const MIN_FIT_OR_STRETCH: Self

Take the smaller of Fit or Stretch.

pub fn contains(self, flags: Self) -> bool

Returns true if all bits in flags are set in self.

pub fn is_stretch(self) -> bool

Returns true if this anchor causes horizontal stretching (both LEFT and RIGHT are set, or MIN/MAX_FIT_OR_STRETCH resolves to stretch).

Trait Implementations

impl BitAnd for HAnchor

type Output = HAnchor

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self

Performs the & operation.

impl BitOr for HAnchor

type Output = HAnchor

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl Clone for HAnchor

fn clone(&self) -> HAnchor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HAnchor

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

Formats the value using the given formatter.

impl Default for HAnchor

fn default() -> Self

Default is FIT: take natural content width.

impl PartialEq for HAnchor

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