Struct RasterStreamWriter 

pub struct RasterStreamWriter { /* private fields */ }

Async raster stream writer.

Accepts chunks via write_chunk and writes a complete GeoTIFF when finalize is called.

Implementations

impl RasterStreamWriter

pub async fn new<P: AsRef<Path>>( path: P, metadata: RasterMetadata, config: RasterStreamConfig, ) -> Result<Self>

Create a new raster stream writer.

pub fn calculate_chunks( width: usize, height: usize, chunk_width: usize, chunk_height: usize, overlap: usize, ) -> (usize, usize)

Calculate the number of chunks needed.

pub async fn write_chunk(&self, chunk: RasterChunk) -> Result<()>

Write a chunk to the raster.

Chunks are stored in memory and written to disk on finalize.

pub async fn write_chunks(&self, chunks: Vec<RasterChunk>) -> Result<()>

Write multiple chunks.

pub async fn stats(&self) -> ChunkStats

Get statistics for written chunks.

pub async fn flush(&self) -> Result<()>

Flush — no-op for the accumulation model (all data is held in memory).

pub async fn finalize(&self) -> Result<()>

Finalize the raster file.

Assembles all accumulated chunks into a contiguous pixel buffer and writes a GeoTIFF using the oxigdal-geotiff driver.

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

Get the total number of chunks.

pub async fn current_position(&self) -> (usize, usize)

Get the current write position (number of chunks written so far).
