Struct WKTGeometryReader 

pub struct WKTGeometryReader {
    pub features: Vec<VectorFeature>,
}

WKT Geometry Reader

Description

Parse a collection of WKT geometries from a string

Implements the FeatureReader trait

Usage

The methods you have access to:

• WKTGeometryReader::new: Create a new WKTGeometryReader

use gistools::{parsers::FeatureReader, readers::WKTGeometryReader};

let collection_wkt = r#"POINT(4 6)
GEOMETRYCOLLECTION(POINT(1 2), LINESTRING(3 4,5 6))
MULTIPOLYGON EMPTY
TRIANGLE((0 0 0,0 1 0,1 1 0,0 0 0))"#;

let reader = WKTGeometryReader::new(collection_wkt.into());
let features: Vec<_> = reader.iter().collect();
assert_eq!(features.len(), 3);

Implementations

impl WKTGeometryReader

pub fn new(data: String) -> Self

Create a new WKT Geometry Reader

pub fn len(&self) -> usize

Get the number of features

pub fn is_empty(&self) -> bool

Check if the reader is empty

Trait Implementations

impl Clone for WKTGeometryReader

fn clone(&self) -> WKTGeometryReader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WKTGeometryReader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FeatureReader<(), Map<String, ValueType>, Map<String, ValueType>> for WKTGeometryReader

A feature reader trait with a callback-based approach

type FeatureIterator<'a> = WKTIterator<'a>

The Feature Reader should implement an iterator of some kind

fn iter(&self) -> Self::FeatureIterator<'_>

All readers have an iter function that returns a Iterator struct

fn par_iter( &self, pool_size: usize, thread_id: usize, ) -> Self::FeatureIterator<'_>

All readers have a par_iter function that returns a ParallelIterator struct
