Struct VisualScene 

pub struct VisualScene<'a> { /* private fields */ }

Ordered collection of uniquely identified visual layers.

Implementations

impl<'a> VisualScene<'a>

pub const fn new() -> Self

Creates an empty scene.

pub fn add_layer(&mut self, layer: VisualLayer<'a>) -> VizResult<()>

Adds a layer, rejecting duplicate identifiers.

pub fn layers(&self) -> &[VisualLayer<'a>]

Returns layers in deterministic insertion order.

pub fn layer(&self, id: &LayerId) -> Option<&VisualLayer<'a>>

Finds a layer by identifier.

pub fn remove_layer(&mut self, id: &LayerId) -> Option<VisualLayer<'a>>

Removes and returns a layer while preserving the order of remaining layers.

Trait Implementations

impl<'a> Clone for VisualScene<'a>

fn clone(&self) -> VisualScene<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for VisualScene<'a>

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

Formats the value using the given formatter.

impl<'a> Default for VisualScene<'a>

fn default() -> VisualScene<'a>

Returns the “default value” for a type.

impl<'a> PartialEq for VisualScene<'a>

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