Enum DatumType 

pub enum DatumType {
    Param3 = 1,
    Param7 = 2,
    GridShift = 3,
    WGS84 = 4,
    NoDatum = 5,
}

Datum Type helps quicker assessment of a datum

Variants

3 Parameter Datum

Param7 = 2

7 Parameter Datum

WGS84 = 4

WGS84 (Base case)

NoDatum = 5

Unknown

Implementations

impl DatumType

pub fn is_params(&self) -> bool

Check if the datum type is 3 or 7

pub fn is_wgs84(&self, params: &DatumParams) -> bool

Check if the datum type is WGS84

Trait Implementations

impl Clone for DatumType

fn clone(&self) -> DatumType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatumType

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

Formats the value using the given formatter.

impl Default for DatumType

fn default() -> DatumType

Returns the “default value” for a type.

impl PartialEq for DatumType

fn eq(&self, other: &DatumType) -> 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 PartialOrd for DatumType

fn partial_cmp(&self, other: &DatumType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
