Struct LegendEntry 

pub struct LegendEntry {
    pub label: String,
    pub from: NodeRef,
    pub properties: Map<String, Value>,
    pub note: Option<String>,
    pub min_zoom: Option<u8>,
    pub max_zoom: Option<u8>,
    pub geometry: Option<LegendGeometry>,
}

One row of a legend: a label, and the symbol it explains identified by where that symbol comes from.

Fields

label: String

What the reader sees. Write it for someone who has not read the style: under $40,000, not bin 0.

from: NodeRef

The node that draws this symbol on the map. Verified at graph-build time to exist and to produce a Raster, so an entry cannot point at something that draws nothing.

properties: Map<String, Value>

Feature properties that select this entry’s case, fed to the node’s *-expr fields the way a real feature would be. For a choropleth, a value inside the class: { "income": 30000 }.

note: Option<String>

Prose for this entry alone.

min_zoom: Option<u8>

Zooms this entry applies to, for a map whose symbols come and go with scale. Absent means every zoom.

max_zoom: Option<u8>

geometry: Option<LegendGeometry>

Which geometry the swatch’s stand-in feature carries. Absent leaves it to whoever draws the swatch, which offers all three.
