Feature properties processing API

Required Methods

fn process_properties<P>(&self, processor: &mut P) -> Result<bool, GeozeroError>

where P: PropertyProcessor,

Process feature properties.

Provided Methods

fn property<T>(&self, name: &str) -> Result<T, GeozeroError>

where T: PropertyReadType,

Get property value by name

An error ColumnNotFound can be interpreted as Null value.

fn property_n<T>(&self, n: usize) -> Result<T, GeozeroError>

where T: PropertyReadType,

Get property value by number

An error ColumnNotFound can be interpreted as Null value.

fn properties(&self) -> Result<HashMap<String, String>, GeozeroError>

Return all properties in a HashMap

Use process_properties for zero-copy access
