Enum vulkano::framebuffer::LoadOp

pub enum LoadOp {
    Load,
    Clear,
    DontCare,
}

Describes what the implementation should do with an attachment at the start of the subpass.

Variants

Load

The attachment will be loaded. This is what you want if you want to draw over something existing.

Clear

The attachment will be cleared by the implementation with a uniform value that you must provide when you start drawing.

This is what you usually use at the start of a frame, in order to reset the content of the color, depth and/or stencil buffers.

See the draw_inline and draw_secondary methods of PrimaryComputeBufferBuilder.

DontCare

The attachment will have undefined content.

This is what you should use for attachments that you intend to overwrite entirely.

Trait Implementations

impl Hash for LoadOp

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Eq for LoadOp

impl PartialEq for LoadOp

fn eq(&self, __arg_0: &LoadOp) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for LoadOp

fn clone(&self) -> LoadOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LoadOp
