BTW I think some anti-Rust people are more annoying than the worst Rust evangelists - seen some of them calling people not using Rust as “murderers”, because “memory leakage can kill at the right time” - but that’s due to them being evangelists to right-wing politics.
When people say “async is viral” in Rust, they mean that once you make one function
async, that change tends to ripple through the rest of your code. Any function that calls it usually has to becomeasyncas well so it canawaitthe result. In turn, the callers of those functions often need to becomeasynctoo.This propagation can continue all the way up the call stack until you reach your application’s entry point. The main exception is when you introduce an explicit synchronous-to-asynchronous boundary, such as by using
block_on, which drives the future to completion without requiring the caller itself to beasync.Yeah but it’s not really a problem with rust but how the language pattern is made. It’s the same in JavaScript/typescript, and Python IIRC
It is Rust implementing the pattern. So… :P
along with most modern languages… it’s the way we deal with async when you don’t want callback hell. it’s just a complex problem domain
like… what… JITs are complex so that’s a problem for V8 specifically?
