Struct LoraPoint 

pub struct LoraPoint {
    pub x: f64,
    pub y: f64,
    pub z: Option<f64>,
    pub srid: u32,
}

A 2D or 3D point, either Cartesian or WGS-84 Geographic.

SRID distinguishes coordinate systems:

• SRID 7203: Cartesian 2D
• SRID 9157: Cartesian 3D
• SRID 4326: WGS-84 Geographic 2D
• SRID 4979: WGS-84 Geographic 3D

z is Some iff the point is 3D. For geographic 3D points z holds the height in metres.

Fields

x: f64

First coordinate: x (Cartesian) or longitude (Geographic)

y: f64

Second coordinate: y (Cartesian) or latitude (Geographic)

z: Option<f64>

Third coordinate: z (Cartesian) or height in metres (Geographic). None for 2D points.

srid: u32

Spatial Reference ID.

Implementations

impl LoraPoint

pub fn cartesian(x: f64, y: f64) -> Self

pub fn cartesian_3d(x: f64, y: f64, z: f64) -> Self

pub fn geographic(longitude: f64, latitude: f64) -> Self

pub fn geographic_3d(longitude: f64, latitude: f64, height: f64) -> Self

pub fn is_geographic(&self) -> bool

True for WGS-84 points (2D or 3D).

pub fn is_3d(&self) -> bool

True for 3D points (Cartesian or WGS-84).

pub fn latitude(&self) -> f64

For geographic points, y is latitude.

pub fn longitude(&self) -> f64

For geographic points, x is longitude.

pub fn height(&self) -> Option<f64>

For geographic 3D points, z is height in metres.

pub fn crs_name(&self) -> &'static str

Canonical CRS name string for this point’s SRID.

Trait Implementations

impl Clone for LoraPoint

fn clone(&self) -> LoraPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoraPoint

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

Formats the value using the given formatter.

impl Display for LoraPoint

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

Formats the value using the given formatter.

impl PartialEq for LoraPoint

fn eq(&self, other: &Self) -> 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.
