Trait nsi::FnFinish

pub trait FnFinish<'a>: FnMut(String, usize, usize, PixelFormat, Vec<f32>) -> Error + 'a { }

A closure which is called once per OutputDriver instance.

It is passed to ɴsɪ via the "callback.finish" attribute on that node.

The closure is called once, before after renderer has finished sending pixels to the output driver.

Example

let finish = nsi::output::FinishCallback::new(
    |name: String,
     width: usize,
     height: usize,
     pixel_format: nsi::output::PixelFormat,
     pixel_data: Vec<f32>| {
        println!(
            "The top, left pixel of the first channel in the {:?} layer has the value {}.",
            pixel_format[0].name(),
            pixel_data[0],
        );
        nsi::output::Error::None
    },
);

ctx.set_attribute(
    "oxidized_output_driver",
    &[
        nsi::string!("drivername", "ferris"),
        // When done, send all pixels to the finish closure.
        nsi::callback!("callback.finish", finish),
    ],
);
