Struct CodesNearest 

pub struct CodesNearest<'a, P: Debug> { /* private fields */ }

The structure used to find nearest gridpoints in CodesMessage.

Implementations

impl<P: Debug> CodesNearest<'_, P>

pub fn find_nearest( &mut 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

 let mut handle = CodesFile::new_from_file("./data/iceland.grib", ProductKind::GRIB)?;
 let msg = handle.ref_message_iter().next()?.context("no message")?;

 let mut 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.
