Enum CrsDef 

pub enum CrsDef {
    Geographic(GeographicCrsDef),
    Projected(ProjectedCrsDef),
    Compound(Box<CompoundCrsDef>),
}

A Coordinate Reference System definition.

Variants

Geographic(GeographicCrsDef)

Geographic CRS (lon/lat in degrees).

Projected(ProjectedCrsDef)

Projected CRS (easting/northing in the CRS’s native linear unit).

Compound(Box<CompoundCrsDef>)

Compound horizontal + vertical CRS.

Implementations

impl CrsDef

pub fn datum(&self) -> &Datum

Get the horizontal datum for this CRS.

pub fn epsg(&self) -> u32

Get the EPSG code for this CRS.

pub fn name(&self) -> &str

Get the CRS name.

pub fn is_geographic(&self) -> bool

Returns true if this CRS’s horizontal component is geographic.

pub fn is_projected(&self) -> bool

Returns true if this CRS’s horizontal component is projected.

pub fn is_compound(&self) -> bool

Returns true if this is a compound horizontal + vertical CRS.

pub fn as_geographic(&self) -> Option<&GeographicCrsDef>

Return the geographic horizontal component, when present.

pub fn as_projected(&self) -> Option<&ProjectedCrsDef>

Return the projected horizontal component, when present.

pub fn vertical_crs(&self) -> Option<&VerticalCrsDef>

Return the explicit vertical CRS component, when this is compound.

pub fn horizontal_crs(&self) -> Option<CrsDef>

Return this CRS’s horizontal component as a standalone CRS definition.

This intentionally drops an explicit vertical component. Use it only for horizontal-only workflows such as AOI filtering, footprint reprojection, and 2D previews where z is outside the operation contract.

pub fn base_geographic_crs_epsg(&self) -> Option<u32>

Returns the geographic CRS EPSG code used for operation selection, when known.

pub fn semantically_equivalent(&self, other: &Self) -> bool

Returns true when two CRS definitions map to the same internal semantics.

Trait Implementations

impl Clone for CrsDef

fn clone(&self) -> CrsDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrsDef

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

Formats the value using the given formatter.

impl TryFrom<CrsDef> for HorizontalCrsDef

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: CrsDef) -> Result<Self>

Performs the conversion.
