Implementations

impl Layers

pub fn new(layer_id: LayerInternalId) -> Self

Creates a new collection of layers, initializing it with the provided first layer.

pub fn len(&self) -> usize

Returns the number of known layers.

pub fn first(&self) -> Rc<RefCell<LayerData>>

Returns the first layer (as Rc).

pub fn last(&self) -> Rc<RefCell<LayerData>>

Returns the last layer (as Rc).

pub fn get(&self, idx: usize) -> Option<Rc<RefCell<LayerData>>>

Returns the layer at the given index, if present.

pub fn push_with_obj(&self, layer_obj: Layer) -> Rc<RefCell<LayerData>>

Adds a layer to the collection by providing a printpdf::Layer object and returns its Rc.

pub fn push_id(&self, layer_id: LayerInternalId) -> Rc<RefCell<LayerData>>

Adds a layer to the collection by providing a LayerInternalId and returns its Rc.

pub fn next(&self, layer: &RefCell<LayerData>) -> Option<Rc<RefCell<LayerData>>>

Returns the layer following the one passed as argument, if it exists.
