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<T>, 

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<T>, 

Get property value by number

An error ColumnNotFound can be interpreted as Null value.

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

Return all properties in a HashMap

Use process_properties for zero-copy access
