Struct glium::framebuffer::EmptyFrameBuffer

pub struct EmptyFrameBuffer { /* fields omitted */ }

pub fn get_max_supported_layers<C: ?Sized>(context: &C) -> Option<u32> where
    C: CapabilitiesSource,

pub fn new<F: ?Sized>(
    facade: &F,
    width: u32,
    height: u32,
    layers: Option<u32>,
    samples: Option<u32>,
    fixed_samples: bool
) -> Result<EmptyFrameBuffer, ValidationError> where
    F: Facade,

Panic

Panics if layers or samples is equal to Some(0).
