Struct Datum 

pub struct Datum {
    pub ellipsoid: Ellipsoid,
    pub to_wgs84: Option<HelmertParams>,
}

A geodetic datum, defined by a reference ellipsoid and its relationship to WGS84.

Fields

ellipsoid: Ellipsoid

The reference ellipsoid.

to_wgs84: Option<HelmertParams>

7-parameter Helmert transformation from this datum to WGS84. None means this datum is WGS84 (or is functionally identical, e.g. NAD83).

Implementations

impl Datum

pub fn is_wgs84_compatible(&self) -> bool

Returns true if this datum is WGS84 or functionally identical (no Helmert shift needed).

pub fn same_datum(&self, other: &Datum) -> bool

Returns true if two datums are the same (same ellipsoid, same Helmert parameters).

Trait Implementations

impl Clone for Datum

fn clone(&self) -> Datum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Datum

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

Formats the value using the given formatter.

impl Copy for Datum
