async/awaitと合成可能性 | κeenのHappy Hacκing Blog
κeenです。async/awaitって実装の都合と利便性の良い所取ってるよなーと常々思ってるのを言語化してインターネットに放流します。 何度か似たようなことを言ってるのですがスライドであることが多くてあまり情報量を詰め込めなかったのでブログにまとめます。 非同期処理と継続 非同期処理は時間のかかる処理を待ち合わせずに別の処理をし、時間のかかる処理が終わってから元の処理を継続する仕組みです。 let url = "http://example.com" let html = fetch url (* この結果を待たずに別の計算をする *) (* fetch urlが終わったあとでここに戻ってきて後続の処理をする *) print html 「継続」や「後続」などのキーワードが出てきているとおり、継続の影がチラチラ見えます。 継続とはいってもスレッドのようなタスク単位で分割したいのでフルの継

Asynchronous Rust
Asynchronous Rust programming is a disaster and a mess. Well, I don’t really mean that. It can actually be rather pleasant, once you get to know it. Some aspects of the async APIs can make you marvel at the infinite genius of the people who designed them, while others make me want to yell the above sentence loudly to anyone who will listen. The truth is, async programming is hard in a language tha

Some thoughts on asynchronous API design in a post-async/await world — njs blog
I've recently been exploring the exciting new world of asynchronous I/O libraries in Python 3 – specifically asyncio and curio. These two libraries make some different design choices. This is an essay that I wrote to try to explain to myself what those differences are and why I think they matter, and distill some principles for designing event loop APIs and asynchronous libraries in Python. This i
I don't understand Python's Asyncio
I don't understand Python's Asyncio written on Sunday, October 30, 2016 Recently I started looking into Python's new asyncio module a bit more. The reason for this is that I needed to do something that works better with evented IO and I figured I might give the new hot thing in the Python world a try. Primarily what I learned from this exercise is that I it's a much more complex system than I expe
How to test Async OCaml code · Andreas Garnæs
How to test Async OCaml code 18 Sep 2014 In the previous blog post, we used Core and Async to write a tiny library for talking to Memcached using the binary protocol. I wanted to write tests for the library in a readable and succint manner to ensure correctness – the type system cannot ensure binary data is parsed correctly after all. The regular go-to tool for testing OCaml code is OUnit, but thi
Taming the Asynchronous Beast with CSP Channels in JavaScript
Taming the Asynchronous Beast with CSP Channels in JavaScript This is an entry in a series about rebuilding my custom blog with react, CSP, and other modern tech. Read more in the blog rebuild series. Every piece of software deals with complex control flow mechanisms like callbacks, promises, events, and streams. Some require simple asynchronous coordination, others processing of event or stream-b
