Struct PreprocessorInvertSelectionBuffer 

pub struct PreprocessorInvertSelectionBuffer(/* private fields */);

The invert selection buffer for Preprocessor.

This is used for inverting the selection in the preprocessor, it is essentially just a boolean.

Implementations

impl PreprocessorInvertSelectionBuffer

pub fn new(device: &Device) -> Self

Create a new invert selection buffer.

Note: the initial value is true.

pub fn update(&self, queue: &Queue, invert: bool)

Update the invert selection buffer.
