Function grib::from_slice

pub fn from_slice(
    bytes: &[u8],
) -> Result<Grib2<SeekableGrib2Reader<Cursor<&[u8]>>>, GribError>

Reads a Grib2 instance from bytes of GRIB2.

Examples

use std::io::Read;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let f = std::fs::File::open(
        "testdata/icon_global_icosahedral_single-level_2021112018_000_TOT_PREC.grib2",
    )?;
    let mut f = std::io::BufReader::new(f);
    let mut buf = Vec::new();
    f.read_to_end(&mut buf).unwrap();
    let result = grib::from_slice(&buf);

    assert!(result.is_ok());
    let grib2 = result?;
    assert_eq!(grib2.len(), 1);
    Ok(())
