Async

• System Threads

  • Kernel-level threads

• Green Threads

  • User-level threads

• Async Implementation at a high level has three major components

  • Executor
  • Reactor
  • XRoutine

• Async

  • Transforms a block of code into a state machine that implements a trait called future

• Await

  • Mechanism to run a future. It asynchronously waits for the future to complete.

• mio provides several core abstractions for working with I/O resources, such as sockets, pipes, and devices.

• It also supports advanced features such as epoll, kqueue, and IOCP on different platforms and convenient utility functions for working with I/O events, timeouts, and buffers.
