Trait geozero::PropertyProcessor

pub trait PropertyProcessor {
    fn property(
        &mut self, 
        idx: usize, 
        name: &str, 
        value: &ColumnValue<'_>
    ) -> Result<bool> { ... }
}

Feature property processing trait.

Usage example:

use geozero::{PropertyProcessor, ColumnValue, error::Result};

struct PropertyPrinter;

impl PropertyProcessor for PropertyPrinter {
    fn property(&mut self, i: usize, n: &str, v: &ColumnValue) -> Result<bool> {
        println!("columnidx: {} name: {} value: {:?}", i, n, v);
        Ok(false) // don't abort
    }
}

Provided methods

fn property(
    &mut self,
    idx: usize,
    name: &str,
    value: &ColumnValue<'_>
) -> Result<bool>

Process property value. Abort processing, if return value is true.
