pub unsafe static kCIContextCVMetalTextureCache: &'static CIContextOptionAvailable on crate feature
CIContext only.Expand description
A Core Video Metal texture cache object to improve the performance of Core Image context renders that use Core Video pixel buffers.
Creating a Core Image context with this optional CVMetalTextureCache can improve the
performance of creating a Metal texture from a CVPixelBuffer. It is recommended
to specify this option if the context renders to or from pixel buffers that come
from a CVPixelBufferPool.
It is the client’s responsibility to flush the cache when appropriate.
