Struct RasterChunk 

pub struct RasterChunk {
    pub buffer: RasterBuffer,
    pub bbox: BoundingBox,
    pub geotransform: GeoTransform,
    pub indices: (usize, usize),
    pub timestamp: DateTime<Utc>,
    pub metadata: ChunkMetadata,
}

A chunk of raster data with spatial metadata.

Fields

buffer: RasterBuffer

The raster data buffer

bbox: BoundingBox

Bounding box of this chunk

geotransform: GeoTransform

Geotransform for this chunk

indices: (usize, usize)

Chunk indices (row, col)

timestamp: DateTime<Utc>

Timestamp when chunk was created

metadata: ChunkMetadata

Chunk metadata

Implementations

impl RasterChunk

pub fn new( buffer: RasterBuffer, bbox: BoundingBox, geotransform: GeoTransform, indices: (usize, usize), ) -> Self

Create a new raster chunk.

pub fn size_bytes(&self) -> usize

Get the size in bytes of this chunk.

pub fn overlaps_with(&self, other: &RasterChunk) -> bool

Check if this chunk overlaps with another.

pub fn overlap_region(&self, other: &RasterChunk) -> Option<BoundingBox>

Get the overlap region with another chunk.

pub fn to_stream_element(&self) -> Result<StreamElement>

Convert to a stream element using JSON serialization of spatial metadata and a raw bytes payload for the raster data.

pub fn from_stream_element(element: &StreamElement) -> Result<Self>

Reconstruct from a stream element. Only the raw pixel buffer and spatial metadata are restored; band-level metadata is left at defaults.

Trait Implementations

impl Clone for RasterChunk

fn clone(&self) -> RasterChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RasterChunk

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

Formats the value using the given formatter.
