Struct Message 

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

A single logical GRIB field.

Implementations

impl<'a> Message<'a>

pub fn edition(&self) -> u8

pub fn index(&self) -> usize

pub fn metadata(&self) -> &MessageMetadata

pub fn reference_time(&self) -> &ReferenceTime

pub fn parameter(&self) -> &Parameter

pub fn center_id(&self) -> u16

pub fn subcenter_id(&self) -> u16

pub fn identification(&self) -> Option<&Identification>

pub fn product_definition(&self) -> Option<&ProductDefinition>

pub fn grib1_product_definition(&self) -> Option<&ProductDefinition>

pub fn local_use_section(&self) -> Option<&'a [u8]>

Returns the complete encoded GRIB2 Section 2, including its five-byte length and section-number header, when present for this field.

pub fn grid_definition(&self) -> &GridDefinition

pub fn parameter_name(&self) -> &str

pub fn parameter_description(&self) -> &str

pub fn forecast_time_unit(&self) -> Option<u8>

pub fn forecast_time_unit_kind(&self) -> Option<ForecastTimeUnit>

pub fn forecast_time(&self) -> Option<i64>

Forecast offset in the units returned by Message::forecast_time_unit.

GRIB2 offsets are signed; GRIB1 offsets are widened to the same type.

pub fn valid_time(&self) -> Option<ReferenceTime>

pub fn grid_shape(&self) -> (usize, usize)

pub fn latitudes(&self) -> Result<Option<Vec<f64>>>

pub fn longitudes(&self) -> Result<Option<Vec<f64>>>

pub fn rotated_latitudes(&self) -> Result<Option<Vec<f64>>>

Latitude axis in the rotated coordinate system for Template 3.1.

pub fn rotated_longitudes(&self) -> Result<Option<Vec<f64>>>

Longitude axis in the rotated coordinate system for Template 3.1.

pub fn projected_x_coordinates(&self) -> Result<Option<Vec<f64>>>

pub fn projected_y_coordinates(&self) -> Result<Option<Vec<f64>>>

pub fn decode_into<T: DecodeSample>(&self, out: &mut [T]) -> Result<()>

Decodes into row-major reader order.

Alternating scan rows are normalized, but the GRIB i/j scan directions are preserved. Use Message::decode_into_north_up when deterministic +i columns and -j rows are required. Bitmap omissions and embedded complex-packing missing codes are written as NaN; substitute metadata is not applied automatically.

pub fn decode_into_north_up<T: DecodeSample>(&self, out: &mut [T]) -> Result<()>

Decodes into deterministic row-major orientation: +i columns and -j rows (north-to-south for conventional geographic grids).

Bitmap omissions and embedded complex-packing missing codes are written as NaN; substitute metadata is not applied automatically.

pub fn read_flat_data_as_f64(&self) -> Result<Vec<f64>>

Returns a flat f64 field in row-major reader order.

Alternating rows are normalized, while encoded i/j directions are preserved. Use Message::read_flat_data_north_up_as_f64 for +i columns and -j rows.

pub fn read_flat_data_as_f32(&self) -> Result<Vec<f32>>

Returns a flat f32 field in row-major reader order.

Alternating rows are normalized, while encoded i/j directions are preserved. Use Message::read_flat_data_north_up_as_f32 for +i columns and -j rows.

pub fn read_flat_data_north_up_as_f64(&self) -> Result<Vec<f64>>

Returns a flat f64 field with +i columns and -j rows.

pub fn read_flat_data_north_up_as_f32(&self) -> Result<Vec<f32>>

Returns a flat f32 field with +i columns and -j rows.

pub fn read_data_as_f64(&self) -> Result<ArrayD<f64>>

Returns an f64 ndarray in row-major reader order.

Alternating rows are normalized, while encoded i/j directions are preserved. Use Message::read_data_north_up_as_f64 for deterministic +i columns and -j rows.

pub fn read_data_as_f32(&self) -> Result<ArrayD<f32>>

Returns an f32 ndarray in row-major reader order.

Alternating rows are normalized, while encoded i/j directions are preserved. Use Message::read_data_north_up_as_f32 for deterministic +i columns and -j rows.

pub fn read_data_north_up_as_f64(&self) -> Result<ArrayD<f64>>

Returns an f64 ndarray with +i columns and -j rows.

pub fn read_data_north_up_as_f32(&self) -> Result<ArrayD<f32>>

Returns an f32 ndarray with +i columns and -j rows.

pub fn raw_bytes(&self) -> &[u8]
