Struct embedded_layout::view_group::EmptyViewGroup

pub struct EmptyViewGroup;

A ViewGroup that contains no View objects.

Trait Implementations

impl Clone for EmptyViewGroup

fn clone(&self) -> EmptyViewGroup

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EmptyViewGroup

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

Formats the value using the given formatter.

impl PartialEq for EmptyViewGroup

fn eq(&self, other: &EmptyViewGroup) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl View for EmptyViewGroup

fn translate_impl(&mut self, _by: Point)

Object-safe version of translate_mut().

fn bounds(&self) -> Rectangle

Returns the bounding box of the View as a Rectangle

fn size(&self) -> Size

Get the size of a View.

fn translate_mut(&mut self, by: Point) -> &mut Selfwhere Self: Sized,

Move the origin of an object by a given number of (x, y) pixels, mutating the object in place.

fn translate(self, by: Point) -> Selfwhere Self: Sized,

Move the origin of an object by a given number of (x, y) pixels, returning a new object.

impl ViewGroup for EmptyViewGroup

fn len(&self) -> usize

Returns the number of View objects in this view group.

fn at(&self, _idx: usize) -> &dyn View

Returns a shared reference the View object at position idx.

fn at_mut(&mut self, _idx: usize) -> &mut dyn View

Returns an exclusive reference to the View object at position idx.

fn bounds_of(&self, idx: usize) -> Rectangle

Returns the bounding box of the given View.

fn translate_child(&mut self, idx: usize, by: Point)

Translates the given View.
