Struct eccodes::codes_nearest::CodesNearest

pub struct CodesNearest<'a> { /* private fields */ }

The structure used to find nearest gridpoints in KeyedMessage.

Implementations

impl CodesNearest<'_>

pub fn find_nearest( &self, lat: f64, lon: f64 ) -> Result<[NearestGridpoint; 4], CodesError>

Function to get four NearestGridpoints of a point represented by requested coordinates.

The inputs are latitude and longitude of requested point in respectively degrees north and degreed east.

Example

  use eccodes::{ProductKind, CodesHandle, KeyedMessage, KeysIteratorFlags};
 use eccodes::FallibleStreamingIterator;
 let file_path = Path::new("./data/iceland.grib");
 let product_kind = ProductKind::GRIB;

 let mut handle = CodesHandle::new_from_file(file_path, product_kind)?;
 let msg = handle.next()?.context("no message")?;

 let c_nearest = msg.codes_nearest()?;
 let out = c_nearest.find_nearest(64.13, -21.89)?;

Errors

This function returns CodesInternal when one of ecCodes function returns the non-zero code.
