Coroutines are computer program components that allow execution to be suspended and resumed, ... Python 2.5 implements better support for coroutine-like functionality
Support for it, coroutines, and the keywords such as co_await are available in GCC and MSVC compilers while Clang has partial support. It is worth noting that std::promise and std::future, although it would seem that they would be awaitable objects, implement none of the machinery required to be returned from coroutines and be awaited using co ...
Python coroutines are similar to standard Python functions (which can return many values in single pass, thanks to Python tuples or dictionaries), but treated quite differently. If the coroutine is first called, it will return another callable object, which then remembers its state (both instruction pointer and local variables) and can be ...
Lua uses coroutines for concurrency. Lua 5.2 also offers true C coroutine semantics through the functions lua_yieldk, lua_callk, and lua_pcallk. The CoCo extension allows true C coroutine semantics for Lua 5.1. Nim provides asynchronous I/O and coroutines; OCaml, since version 5.0, supports green threads through the Domainslib.Task module
In Python, a generator can be thought of as an iterator that contains a frozen stack frame. Whenever next() is called on the iterator, Python resumes the frozen frame, which executes normally until the next yield statement is reached. The generator's frame is then frozen again, and the yielded value is returned to the caller.
Coroutines are functions that can yield control to each other - a form of co-operative multitasking without threads. Coroutines can be implemented as a library if the programming language provides either continuations or generators - so the distinction between coroutines and generators in practice is a technical detail.
In computer science, futures, promises, delays, and deferreds are constructs used for synchronizing program execution in some concurrent programming languages.Each is an object that acts as a proxy for a result that is initially unknown, usually because the computation of its value is not yet complete.
In computer science, a continuation is an abstract representation of the control state of a computer program.A continuation implements the program control state, i.e. the continuation is a data structure that represents the computational process at a given point in the process's execution; the created data structure can be accessed by the programming language, instead of being hidden in the ...
