}Expand description
Temporarily convert colors in place. The Into counterpart to
FromColorMut.
See FromColorMut for more details and examples.

);Required Methods§
sourcefn into_color_mut(&mut self) -> FromColorMutGuard<'_, T, Self>
fn into_color_mut(&mut self) -> FromColorMutGuard<'_, T, Self>
Temporarily convert to another color type in place.
This reuses the memory space, and the returned scope guard will restore the converted colors to their original type when it’s dropped.
Object Safety§
This trait is not object safe.
