Blocking IO methods use Condvars to prevent busy-wait loops. DPDK also offers memory pools library to allocate/deallocate buffers between multiple threads or processes. Let’s explore five essential techniques for creating robust implementations. Can be used without std and even without alloc (using only statically-allocated memory). Sometimes it may spin the CPU for a bit if there is a contention on a single element in the buffer for write and read operations. This crate is `#! [no_std]` and uses `alloc` internally; it provides a minimal, ergonomic API that works well from `no_std` contexts that supply an allocator as well as from normal `std` programs and examples.
