Enum DatumToWgs84 

pub enum DatumToWgs84 {
    Identity,
    Helmert(HelmertParams),
    GridShift(Box<DatumGridShift>),
    Unknown,
}

Explicit WGS84 relationship for a datum.

Variants

Identity

The datum can be treated as WGS84-compatible in the current model.

Helmert(HelmertParams)

The datum requires the provided Helmert transform to reach WGS84.

GridShift(Box<DatumGridShift>)

The datum requires horizontal grid interpolation to reach WGS84.

Unknown

The datum’s path to WGS84 is not known.

Implementations

Trait Implementations

impl Clone for DatumToWgs84

fn clone(&self) -> DatumToWgs84

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatumToWgs84

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

Formats the value using the given formatter.

impl PartialEq for DatumToWgs84

fn eq(&self, other: &DatumToWgs84) -> 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.
