Struct Appearance 

pub struct Appearance {
    pub materials: Option<Vec<MaterialObject>>,
    pub textures: Option<Vec<TextureObject>>,
    pub vertices_texture: Option<Vec<[f64; 2]>>,
    pub default_theme_texture: Option<String>,
    pub default_theme_material: Option<String>,
}

The document-level appearance library.

cityjson.schema.json#/properties/appearance names five members and then declares "additionalProperties": false, exactly as the MaterialObject and TextureObject it contains do — cityjsonfeature.schema.json#/properties/appearance carries the same clause verbatim, so the rule holds at both document levels. Hence deny_unknown_fields here too: an extra member is not CityJSON, and dropping it silently at this level while rejecting it one level down would be inconsistent as well as lossy.

Fields

materials: Option<Vec<MaterialObject>>

textures: Option<Vec<TextureObject>>

vertices_texture: Option<Vec<[f64; 2]>>

The (u, v) texture vertices. The schema pins each one to minItems: 2, maxItems: 2, so it is [f64; 2] and not Vec<f64>: a fixed-size array rejects a 1- or 3-element vertex on read and makes one unwritable, exactly as [f64; 3] does for a colour and [f64; 6] for a geographical extent.

default_theme_texture: Option<String>

default_theme_material: Option<String>
