lwtversion
Promises and event-driven I/O
A promise is a value that may become determined in the future.
Lwt provides typed, composable promises. Promises that are resolved by I/O are resolved by Lwt in parallel.
Meanwhile, OCaml code, including code creating and waiting on promises, runs in a single thread by default. This reduces the need for locks or other synchronization primitives. Code can be run in parallel on an opt-in basis.
