Struct ViewerState 

pub struct ViewerState {
    pub version: u32,
    pub camera: Camera,
    pub viewport: ViewportSize,
    pub layers: Vec<LayerPresentation>,
    pub selected_layer: Option<LayerId>,
    pub pending_files: Vec<String>,
}

Portable state shared by native, Web, Python, and notebook surfaces.

Fields

version: u32

Schema version, currently VIEWER_STATE_VERSION.

camera: Camera

Active camera.

viewport: ViewportSize

Logical viewport dimensions.

layers: Vec<LayerPresentation>

Ordered layer presentation state.

selected_layer: Option<LayerId>

Selected layer identity.

pending_files: Vec<String>

Validated data files queued by native drag/drop.

Implementations

impl ViewerState

pub fn try_new(camera: Camera, viewport: ViewportSize) -> ViewerResult<Self>

Creates an empty viewer state.

pub fn validate(&self) -> ViewerResult<()>

Validates the complete portable state before it is handed to a renderer, serialized, or embedded in a larger Studio state.

pub fn sync_scene(&mut self, scene: &VisualScene<'_>)

Synchronizes layer metadata from a borrowed visual scene.

Existing visibility and style edits are retained for matching stable IDs.

pub fn set_layer_visible( &mut self, id: &LayerId, visible: bool, ) -> ViewerResult<()>

Changes a layer’s visibility.

pub fn select_layer(&mut self, id: Option<&LayerId>) -> ViewerResult<()>

Selects a layer for attribute inspection.

pub fn set_layer_style( &mut self, id: &LayerId, style: VisualStyle, ) -> ViewerResult<()>

Replaces the visual style after validating attribute compatibility.

pub fn inspector(&self) -> Option<InspectorSelection<'_>>

Returns the selected layer and active point attribute.

pub fn queue_dropped_file( &mut self, path: impl Into<String>, ) -> ViewerResult<()>

Queues a supported point-cloud file from drag/drop.

Trait Implementations

impl Clone for ViewerState

fn clone(&self) -> ViewerState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewerState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ViewerState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ViewerState

fn eq(&self, other: &ViewerState) -> 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.

impl Serialize for ViewerState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
