Struct shapefile::writer::Writer

pub struct Writer<T: Write> {
    pub dest: T,
    // some fields omitted
}

struct that writes the shapes

Fields

dest: T

Methods

impl<T: Write> Writer<T>

pub fn new(dest: T) -> Self

Creates a writer that can be used to write a new shapefile.

The dest argument is only for the .shp

pub fn write_shapes<S: EsriShape>(     &mut self,     shapes: Vec<S> ) -> Result<(), Error>

Writes the shapes to the file

Examples

use shapefile::Point;
let mut writer = shapefile::Writer::from_path("points.shp").unwrap();
let points = vec![Point::new(0.0, 0.0), Point::new(1.0, 0.0), Point::new(2.0, 0.0)];

writer.write_shapes(points).unwrap();

use shapefile::{Point, Polyline};
let mut writer = shapefile::Writer::from_path("polylines.shp").unwrap();
let points = vec![Point::new(0.0, 0.0), Point::new(1.0, 0.0), Point::new(2.0, 0.0)];
let polyline = Polyline::new(points, vec![0]);

writer.write_shapes(vec![polyline]).unwrap();

pub fn add_index_dest(&mut self, dest: T)

Adds dest as the destination where the index file will be written

impl Writer<BufWriter<File>>

pub fn from_path<P: AsRef<Path>>(path: P) -> Result<Self, Error>

Creates a new writer from a path. Creates both a .shp and .shx files

Examples

let writer = shapefile::Writer::from_path("/dev/null");
