Struct CubeWriter 

pub struct CubeWriter { /* private fields */ }

A streaming writer that holds an initialised output cube open for the lifetime of a processing run, so channels can be written one at a time without the per-call file open/close overhead of write_channel.

cfitsio drives a single file through one internal cursor and is not thread-safe, so a CubeWriter must be owned and driven by a single thread (the consumer end of the streaming pipeline in main).

Implementations

impl CubeWriter

pub fn open(path: &Path) -> Result<Self, CubeError>

Open an already-initialised output cube (see init_output_cube) for sequential channel writes.

pub fn write_channel_as<T: CubeElem>( &mut self, chan: usize, data: &Array2<T>, meta: &CubeMeta, ) -> Result<(), CubeError>

Write one frequency channel plane (precision T) into the open cube.

pub fn write_channel( &mut self, chan: usize, data: &Array2<f32>, meta: &CubeMeta, ) -> Result<(), CubeError>

Write one f32 frequency channel plane (see CubeWriter::write_channel_as).
