Struct libreda_db::layout::shape_collection::Shapes

pub struct Shapes<T> where
    T: CoordinateType,  { /* fields omitted */ }

Shapes<T> is a collection of Shape<T> structs. Each of the elements is assigned an index when inserted into the collection.

Implementations

impl<T: CoordinateType> Shapes<T>

pub fn new_rc() -> Rc<Self>

Create a new shapes object. It is not associated with any cell.

pub fn from_geometries<I: IntoIterator<Item = Geometry<T>>>(iter: I) -> Rc<Self>

Create a new Shapes object and populate it with the geometries from the iterator.

pub fn insert<I: Into<Geometry<T>>>(&self, shape: I) -> Rc<Shape<T>>

Add a shape to the collection.

pub fn remove_shape(&self, shape: &Shape<T>)

Remove the shape from the collection if it exists. TODO: What if a shape from another Shapes collection is passed here?

pub fn len(&self) -> usize

Return number of shapes in this container.

pub fn is_empty(&self) -> bool

Tell if there are not shapes stored in this container.

pub fn each_shape(&self) -> impl Iterator<Item = Rc<Shape<T>>> + '_

Iterator over all shapes.

pub fn with_shape_iter<F, R>(&self, f: F) -> R where
    F: FnOnce(Values<'_, Index<Shape<T>>, Rc<Shape<T>>>) -> R, 

Iterate over all shapes.

pub fn for_each_shape<F>(&self, f: F) where
    F: FnMut(&Rc<Shape<T>>), 

Call a closure on each shape.

pub fn parent_cell(&self) -> Weak<Cell<T>>

Get weak reference to the parent cell if there is any.

Trait Implementations

impl<T: Clone> Clone for Shapes<T> where
    T: CoordinateType, 

fn clone(&self) -> Shapes<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Shapes<T> where
    T: CoordinateType, 

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

Formats the value using the given formatter.

impl<T: Default> Default for Shapes<T> where
    T: CoordinateType, 

fn default() -> Shapes<T>

Returns the "default value" for a type.

impl<T: CoordinateType> TryBoundingBox<T> for Shapes<T>

fn try_bounding_box(&self) -> Option<Rect<T>>

Return the bounding box of this geometry if a bounding box is defined.
