Expand description

A placed symbol after collision resolution.

Fields§

§id: String

Stable symbol id.

§layer_id: Option<String>

Originating style/runtime layer id, when known.

§source_id: Option<String>

Originating style source id, when known.

§source_layer: Option<String>

Originating style source-layer id, when known.

§source_tile: Option<TileId>

Tile that supplied the symbol feature, when known.

§feature_id: String

Stable feature id for feature-state and queries.

§feature_index: usize

Source-local feature index.

§placement: SymbolPlacement

Whether this symbol is point-placed or line-placed.

§anchor: GeoCoord

Geographic anchor point.

§world_anchor: [f64; 3]

World-space anchor point.

§text: Option<String>

Optional text content.

§icon_image: Option<String>

Optional icon image id.

§font_stack: String

Font stack for text rendering.

§cross_tile_id: String

Stable cross-tile identity.

§rotation_rad: f32

Clockwise screen-space rotation in radians for rendering.

§collision_box: SymbolCollisionBox

Collision box used during placement.

§anchor_mode: SymbolAnchor

Selected anchor used for this placement.

§writing_mode: SymbolWritingMode

Writing mode used for this placement.

§offset_px: [f32; 2]

Pixel-space offset applied during placement.

§radial_offset: Option<f32>

Optional radial offset measured in symbol-size units.

§text_max_width: Option<f32>

Maximum point-label width before wrapping.

§text_line_height: Option<f32>

Preferred wrapped text line height.

§text_letter_spacing: Option<f32>

Extra spacing between adjacent glyphs.

§icon_text_fit: SymbolIconTextFit

Icon sizing mode relative to the text box.

§icon_text_fit_padding: [f32; 4]

Padding applied when fitting the icon around text.

§size_px: f32

Nominal symbol size in pixels.

§fill_color: [f32; 4]

Placeholder fill colour used by current renderers.

§halo_color: [f32; 4]

Placeholder halo colour used by current renderers.

§opacity: f32

Fade opacity in [0, 1].

§visible: bool

Whether the symbol survived collision placement this frame.

§glyph_quads: Vec<GlyphQuad>

Pre-computed glyph positions relative to the symbol anchor (pixels).

Populated by layout_symbol_glyphs. When non-empty the renderer uses these quads directly; when empty it falls back to naive character-by-character layout.
