How a grid’s points map to the Earth.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

#[non_exhaustive]

LatLon

Template 3.0: points evenly spaced in latitude and longitude.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

first_lat_deg: f64

The first point’s latitude, degrees north.

first_lon_deg: f64

The first point’s longitude, degrees east, in [0, 360) as GRIB writes it.

di_deg: f64

The spacing in longitude between neighbouring points along i, degrees.

dj_deg: f64

The spacing in latitude between neighbouring points along j, degrees.

#[non_exhaustive]

LambertConformal

Template 3.30: a Lambert conformal conic projection, on a tangent cone.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

first_lat_deg: f64

The first point’s latitude, degrees north.

first_lon_deg: f64

The first point’s longitude, degrees east.

tangent_lat_deg: f64

The latitude where the cone touches the sphere (Latin1 = Latin2 = LaD), degrees.

orientation_lon_deg: f64

The meridian parallel to the grid’s y axis (LoV), degrees east.

dx_m: f64

The grid spacing along x at the tangent latitude, m.

dy_m: f64

The grid spacing along y at the tangent latitude, m.

radius_m: f64

The sphere’s radius, m.

Trait Implementations

impl Clone for Projection

fn clone(&self) -> Projection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Projection

impl Debug for Projection

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Projection

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Projection

fn eq(&self, other: &Projection) -> 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 Serialize for Projection

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Projection
