Enum ElementRef

pub enum ElementRef<'a, L> {
    Instance(&'a RawInstance<L>),
    Shape(&'a Shape<L>),
    Text(&'a Text<L>),
}

A pointer to a primitive layout element.

Variants

Instance(&'a RawInstance<L>)

A raw layout instance.

Shape(&'a Shape<L>)

A primitive layout shape.

Text(&'a Text<L>)

A primitive text annotation.

Implementations

impl<'a, L> ElementRef<'a, L>

pub fn instance(self) -> Option<&'a RawInstance<L>>

If this is an Instance variant, returns the contained instance. Otherwise, returns None.

pub fn shape(self) -> Option<&'a Shape<L>>

If this is a Shape variant, returns the contained shape. Otherwise, returns None.

pub fn text(self) -> Option<&'a Text<L>>

If this is a Text variant, returns the contained text. Otherwise, returns None.

Trait Implementations

impl<L> Bbox for ElementRef<'_, L>

fn bbox(&self) -> Option<Rect>

Computes the axis-aligned rectangular bounding box.

fn bbox_rect(&self) -> Rect

Computes the axis-aligned rectangular bounding box, panicking if it is empty.

impl<'a, L: Clone> Clone for ElementRef<'a, L>

fn clone(&self) -> ElementRef<'a, L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, L: Debug> Debug for ElementRef<'a, L>

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

Formats the value using the given formatter.

impl<'a, L> From<&'a RawInstance<L>> for ElementRef<'a, L>

fn from(value: &'a RawInstance<L>) -> Self

Converts to this type from the input type.

impl<'a, L> From<&'a Shape<L>> for ElementRef<'a, L>

fn from(value: &'a Shape<L>) -> Self

Converts to this type from the input type.

impl<'a, L> From<&'a Text<L>> for ElementRef<'a, L>

fn from(value: &'a Text<L>) -> Self

Converts to this type from the input type.

impl<L: PartialEq> LayerBbox<L> for ElementRef<'_, L>

fn layer_bbox(&self, layer: &L) -> Option<Rect>

Compute the bounding box considering only objects occupying the given layer.

impl<'a, L: PartialEq> PartialEq for ElementRef<'a, L>

fn eq(&self, other: &ElementRef<'a, L>) -> 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.
