Struct StreamArg 

pub struct StreamArg<T> { /* private fields */ }

A typed external argument for a CommandStream.

StreamArg values are created with CommandStreamMut::arg while building a stream and are later bound to parent-graph nodes with CommandStreamRun::with_arg.

let stream = CommandStream::finalize(|stream| {
    stream.arg(ImageInfo::image_2d(
        640,
        480,
        vk::Format::R8G8B8A8_UNORM,
        vk::ImageUsageFlags::COLOR_ATTACHMENT,
    ))
})
.into_stream();

let mut graph = Graph::new();
graph
    .insert_cmd_stream(&stream)
    .with_arg(stream.args, swapchain_image)
    .finish();

impl<T: Ord> Ord for StreamArg<T>

fn cmp(&self, other: &StreamArg<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl<T: PartialEq> PartialEq for StreamArg<T>

fn eq(&self, other: &StreamArg<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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