Struct nannou::wgpu::Textue5cfe74reSnapshot [−][src]
pub struct Textue5cfe74reSnapshot { /* fields omitted */ }
Expand description
A snapshot captured by a Capturer.
A snapshot is a thin wrapper around a wgpu::BufferImage that knows that the image format is specifically non-linear sRGBA8.
Implementations
pub async fn read_async<'buffer>(
&'buffer self
) -> Result<Rgba8AsyncMappedImageBuffer<'buffer>, BufferAsyncError>
pub async fn read_async<'buffer>(
&'buffer self
) -> Result<Rgba8AsyncMappedImageBuffer<'buffer>, BufferAsyncError>
Reads the non-linear sRGBA image from mapped memory and convert it to an owned buffer.
The same as read_async
, but runs the resulting future on an inner threadpool and calls
the given callback with the mapped image buffer once complete.
Note: The given callback will not be called until the memory is mapped and the device is polled. You should not rely on the callback being called immediately.
Note: The given callback will be called on the inner thread pool and will not be called on the current thread.
Note: This method may block if the associated wgpu::TextureCapturer
has an
active_futures
count that is greater than the number of worker threads with which it was
created. This is necessary in order to avoid “out of memory” errors resulting from an
accumulating queue of pending texture buffers waiting to be mapped. To avoid blocking, you
can try using a higher thread count, capturing a smaller texture, or using read_async
instead and running the resulting future on a custom runtime or threadpool.
