Expand description

enum of Shapes that can be read or written to a shapefile

§geo-types

shapefile::Shape and geo_types::Geometry<f64> can be converted from one to another, however this conversion is not infallible so it is done using TryFrom

use std::convert::TryFrom;
use shapefile::Shape;
let mut shapes = shapefile::read_shapes("tests/data/line.shp")?;
let last_shape = shapes.pop().unwrap();
let geometry = geo_types::Geometry::<f64>::try_from(last_shape);

assert_eq!(geometry.is_ok(), true);
assert_eq!(geo_types::Geometry::<f64>::try_from(Shape::NullShape).is_err(), true);

impl ReadableShape for Shape

fn read_from<T: Read>(source: &mut T, record_size: i32) -> Result<Self, Error>

impl TryFrom<Geometry> for Shape

Converts a Geometry to a Shape

Since all Geometries are in 2D, the resulting shape will be 2D (Polygon, Polyline, etc and not PolylineM, PolylineZ, etc)

Fails if the geometry is a GeometryCollection, Rect, or Triangle

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(geometry: Geometry<f64>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for Multipoint

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for MultipointM

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for MultipointZ

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for Polygon

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for PolygonM

type Error = Error

The type returned in the event of a conversion error.

impl TryFrom<Shape> for PolygonZ

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for Polyline

type Error = Error

The type returned in the event of a conversion error.

Performs the conversion.

impl TryFrom<Shape> for PolylineZ

type Error = Error

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Shape> for Geometry<f64>

Tries to convert a shapefile’s Shape into a geo_types::Geometry

This conversion can fail because the conversion of shapefile’s polygons & multipatch into their geo_types counter parts can fail. And the NullShape has no equivalent Geometry;

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(shape: Shape) -> Result<Self, Self::Error>

Performs the conversion.
