Implementations

impl StyleLayer

pub fn id(&self) -> &str

Layer id.

pub fn meta(&self) -> &StyleLayerMeta

Shared metadata.

pub fn meta_mut(&mut self) -> &mut StyleLayerMeta

Shared metadata, mutable.

pub fn to_runtime_layer_with_context( &self, sources: &HashMap<StyleSourceId, StyleSource>, ctx: StyleEvalContext, ) -> Result<Box<dyn Layer>, StyleError>

Evaluate into a concrete runtime layer with a context.

pub fn apply_to_runtime_layer_with_context( &self, runtime: &mut dyn Layer, sources: &HashMap<StyleSourceId, StyleSource>, ctx: StyleEvalContext, ) -> Result<(), StyleError>

Apply evaluated paint/layout state onto an existing runtime layer.

pub fn source_id(&self) -> Option<&str>

Return the referenced source id, if this layer is source-backed.

pub fn source_layer(&self) -> Option<&str>

Return the referenced source-layer name, if this layer targets a named source layer within a vector-tile-like source.

pub fn uses_source(&self, source_id: &str) -> bool

Return true if this layer references the given source id.

pub fn has_feature_state_driven_paint(&self) -> bool

Whether any paint property on this layer uses a FeatureState value.

This lets callers skip per-feature re-evaluation for layers that only use constant or zoom-keyed paint properties.

pub fn resolve_style_with_feature_state( &self, ctx: &StyleEvalContextFull<'_>, ) -> Option<VectorStyle>

Resolve the layer’s paint properties against a full evaluation context that includes per-feature mutable state.

Returns Some(VectorStyle) for vector-backed layer families, or None for layer types that do not produce a VectorStyle (background, hillshade, raster, model).

This is the primary entry point for hover/selection-driven restyling: the caller builds a StyleEvalContextFull with the target feature’s current state, then receives a resolved VectorStyle that can be compared or applied to the feature’s visual representation.

Trait Implementations

impl Clone for StyleLayer

fn clone(&self) -> StyleLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StyleLayer

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