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).

pub fn bits(self) -> u8

Raw bit value — used by the inspector to store/cycle anchor presets.

pub fn display_name(self) -> &'static str

Short display name for the inspector properties pane.

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 FromReflect for HAnchor

fn from_reflect(reflect: &dyn PartialReflect) -> Option<Self>

Constructs a concrete instance of Self from a reflected value.

fn take_from_reflect( reflect: Box<dyn PartialReflect>, ) -> Result<Self, Box<dyn PartialReflect>>

Attempts to downcast the given value to Self using, constructing the value using from_reflect if that fails.

impl GetTypeRegistration for HAnchor

fn get_type_registration() -> TypeRegistration

Returns the default TypeRegistration for this type.

fn register_type_dependencies(_registry: &mut TypeRegistry)

Registers other types needed by this type.

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.

Tries to apply a reflected value to this value.

fn reflect_kind(&self) -> ReflectKind

Returns a zero-sized enumeration of “kinds” of type.

fn reflect_ref(&self) -> ReflectRef<'_>

Returns an immutable enumeration of “kinds” of type.

fn reflect_mut(&mut self) -> ReflectMut<'_>

Returns a mutable enumeration of “kinds” of type.

fn try_as_reflect(&self) -> Option<&dyn Reflect>

Attempts to cast this type to a fully-reflected value.

fn try_as_reflect_mut(&mut self) -> Option<&mut dyn Reflect>

Attempts to cast this type to a mutable, fully-reflected value.

fn into_partial_reflect(self: Box<Self>) -> Box<dyn PartialReflect>

Casts this type to a boxed, reflected value.

fn as_partial_reflect(&self) -> &dyn PartialReflect

Casts this type to a reflected value.

fn as_partial_reflect_mut(&mut self) -> &mut dyn PartialReflect

Casts this type to a mutable, reflected value.

fn apply(&mut self, value: &(dyn PartialReflect + 'static))

Applies a reflected value to this value.

fn reflect_clone(&self) -> Result<Box<dyn Reflect>, ReflectCloneError>

Attempts to clone Self using reflection.

fn reflect_clone_and_take<T>(&self) -> Result<T, ReflectCloneError>

where T: 'static, Self: Sized + TypePath,

For a type implementing PartialReflect, combines reflect_clone and take in a useful fashion, automatically constructing an appropriate ReflectCloneError if the downcast fails.

fn reflect_hash(&self) -> Option<u64>

Returns a hash of the value (which includes the type).

fn reflect_partial_eq( &self, _value: &(dyn PartialReflect + 'static), ) -> Option<bool>

Returns a “partial equality” comparison result.

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