Struct FeatureWriter 

pub struct FeatureWriter<'a> { /* private fields */ }

A writer that converts CityJSON features to FlatBuffers format

This struct handles the serialization of CityJSON features into a binary FlatBuffers representation, which is more efficient for storage and transmission.

Implementations

impl<'a> FeatureWriter<'a>

pub fn new( city_feature: &'a CityJSONFeature, attr_schema: AttributeSchema, semantic_attr_schema: Option<AttributeSchema>, attr_indices: Option<Vec<String>>, ) -> FeatureWriter<'a>

Creates a new FeatureWriter instance

Arguments

• city_feature - A reference to the CityJSON feature to be serialized

pub fn finish_to_feature(&mut self) -> Vec<u8>

Serializes the current feature to a FlatBuffers binary format

This method converts the CityJSON feature into a FlatBuffers representation, including all city objects and vertices. The resulting buffer is size-prefixed.

Returns

A vector of bytes containing the serialized feature

pub fn add_feature(&mut self, feature: &'a CityJSONFeature)

Updates the writer with a new feature to be serialized

Arguments

• feature - A reference to the new CityJSON feature
