Struct Slot 

struct Slot {
    buffer: Buffer,
    size: u64,
    writable: Arc<AtomicBool>,
}

One staging buffer and whether the host may write into its mapping.

Fields

buffer: Buffer

The staging buffer itself: host-writable and copyable from.

size: u64

Size in bytes.

writable: Arc<AtomicBool>

Whether the host owns the mapping, and so may write the next upload into this buffer. Set when the buffer is created mapped and again by the mapping callback; cleared by every write.

Implementations

impl Slot

fn new(device: &Device, size: u64) -> Self

Allocate a buffer of size bytes, mapped and ready to be written.

fn can_reuse(&self, size: u64) -> bool

Whether this buffer is writable and holds at least size bytes.
