Function read_raster_band_async

pub async fn read_raster_band_async<T: RasterType>(
    s3_url: &str,
    band_index: usize,
    offset: (isize, isize),
    window_size: (usize, usize),
) -> Result<Array2<T>>

Read a raster band window using async-tiff (S3 direct, no GDAL).

This is the async equivalent of gdal_utils::read_raster_band(). Uses a cached TIFF reader for efficiency.

Arguments

• s3_url - S3 URL like “s3://bucket/path/to/file.tif”
• band_index - Band index (1-based, like GDAL)
• offset - (x_offset, y_offset) in pixels
• window_size - (width, height) in pixels
