Struct framebuffer_compositor::CacheBlock

pub struct CacheBlock { /* private fields */ }

A CacheBlock represents the cached (previously-composited) content of a range of rows in the source framebuffer. It specifies the rectangular region in the destination framebuffer and the hash. Once cached, a CacheBlock block is independent of the source framebuffer it came from. content_hash is the hash value of the actual pixel contents in the cached block. A cache block is identical to some new framebuffer rows to be updated if they share the same content_hash, location and width.

Implementations
