Struct FcbWriter 

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

Main writer for FlatCityBuf (FCB) format

FcbWriter handles the serialization of CityJSON data into the FCB binary format. It manages both header and feature writing, using a temporary file for feature storage before final assembly.

Implementations

impl<'a> FcbWriter<'a>

pub fn new( cj: CityJSON, header_option: Option<HeaderWriterOptions>, attr_schema: Option<AttributeSchema>, semantic_attr_schema: Option<AttributeSchema>, ) -> Result<Self>

Creates a new FCB writer instance

Arguments

• cj - The CityJSON data to be written
• header_option - Optional configuration for header writing
• first_feature - Optional first feature to begin writing

Returns

A Result containing the new FcbWriter instance

pub fn add_feature(&mut self, feature: &'a CityJSONFeature) -> Result<()>

Adds a new feature to be written

Arguments

• feature - The CityJSON feature to add

Returns

A Result indicating success or failure of the operation

pub fn write(self, out: impl Write) -> Result<()>

Writes the complete FCB dataset to the output

This method assembles the final FCB file by writing:

1. Magic bytes
2. Header
3. Feature data

Arguments

• out - The output destination implementing Write

Returns

A Result indicating success or failure of the write operation
