Line layer style spec.

Fields

meta: StyleLayerMeta

source: StyleSourceId

source_layer: Option<String>

Optional source-layer name for vector-tile-like sources.

color: StyleValue<[f32; 4]>

width: StyleValue<f32>

line_cap: LineCap

Line cap style (default: butt).

line_join: LineJoin

Line join style (default: miter).

miter_limit: f32

Miter limit ratio (default: 2.0).

dash_array: Option<Vec<f32>>

Optional dash pattern [dash, gap, …] in pixels.

line_gradient: Option<ColorRamp>

Optional colour ramp evaluated along the line’s length.

When set, per-vertex colours are overridden by the gradient evaluated at each vertex’s normalized distance [0, 1] along the polyline. Replaces line-color (matching MapLibre / Mapbox line-gradient semantics).

line_pattern: Option<Arc<PatternImage>>

Optional repeating pattern image for textured line rendering.

When set, the line is rendered with a repeating pattern texture instead of a solid colour, matching MapLibre / Mapbox line-pattern semantics.
