Struct CassiniProjection 

pub struct CassiniProjection { /* private fields */ }

Cassini (Cassini-Soldner) Projection

Although the Cassini projection has been largely replaced by the Transverse Mercator, it is still in limited use outside the United States and was one of the major topographic mapping projections until the early 20th century.

Classification: Transverse and oblique cylindrical

Available forms: Forward and Inverse, Spherical and ellipsoidal

Defined area: Global, but best used near the central meridian with long, narrow areas

Alias: cass

Domain: 2D

Input type: Geodetic coordinates

Output type: Projected coordinates

Projection String

+proj=cass

Required Parameters

• lat_0

Optional Parameters

• lon_0
• x_0
• y_0
• ellps
• R
• +hyperbolic: Use modified form of the standard Cassini-Soldner projection known as the Hyperbolic Cassini-Soldner (used in EPSG:3139).

Trait Implementations

impl Clone for CassiniProjection

fn clone(&self) -> CassiniProjection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CoordinateStep for CassiniProjection

fn new(proj: Rc<RefCell<Proj>>) -> Self

Create a new Converter

fn forward<P: TransformCoordinates>(&self, p: &mut P)

forward conversion

fn inverse<P: TransformCoordinates>(&self, p: &mut P)

inverse conversion

impl Debug for CassiniProjection

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

Formats the value using the given formatter.

impl PartialEq for CassiniProjection

fn eq(&self, other: &CassiniProjection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ProjectCoordinates for CassiniProjection

fn code(&self) -> i64

ESPG code for this projection

fn name(&self) -> &'static str

Projection name

fn names() -> &'static [&'static str]

Returns the list of canonical names for this projection. This is an associated function, similar to a static method.

fn datum_type() -> u8

get the datum type. Defaults to no datum
