This is intended to a Rust analog to "src/util", which has
many utilities used by Mesa developers. This is mostly
a copy of ${crosvm} rutabaga_gfx/src/rutabaga_os (which will
be deleted in favor of this crate).
Key constructs include:
- SharedMemory
- MemoryMapping
- Tube (sockets, essentially)
- OwnedDescriptor (HANDLE or fd-based)
- WaitContext (epoll, ..)
As one would expect, Linux implementations are the most complete.
