What's the Benefit/Allure of Async/Await vs. CSP/Green Threads (and Other Concurrency Models)?

   rust stackful coroutine library

   

   It seems that rust removed native green threads as against it's philosophy: https://stackoverflow.com/questions/29428318/why-did-rust-remove-the-green-threading-model-whats-the-disadvantage#29430403 but there are good CSP libraries e.g. https://github.com/Xudong-Huang/may and yet people really like e.g. Tokio for Async/Await (although it also has greenthreads!) What am I missing?

   lot of unsafe code assumes you can't leak stackframes, which suspendable APIs however inherently can, hence why scoped tasks are unsound. This is not different with green threads, see for example this issue in generator, the library that may uses for green threads.

   This repository has examples of broken patterns in ASP.NET Core applications

   

   The C# (mostly applicat community has e.g. https://github.com/davidfowl/AspNetCoreDiagnosticScenarios/blob/master/AsyncGuidance.md written by one of the Asp.Net architects. I found this in this lovely thread https://news.ycombinator.com/item?id=36785691 which expresses my views/confusion more clearly than I can express.
