Thanks for coming resources: https://gist.github.com/MattPD/9b55db49537a90545a90447392ad3aeb Before we dive into the system, I want to take 10 mins to have a quick recap about C++ coroutine and share some gotcha moments pretty overwhelmed by all different terms, not to mention to put them up together to form a knowledge system. I hope the following information can be helpful and I attached some links in the slides, or pointers

from Columbia University. Title : Behavior-driven Tests for Microservices-based Algo Trading System Summary : Introduction : This poster will introduce a test framework we use at Bloomberg to to enable behavior-based tests in natural language style for a microservices-based algo trading system that our engineering team is responsible for. Relevance : For our electronic trading business Although microservice components can easily be unit tested, it is often non-trivial to automate the system-level tests with external dependencies. Controlling external dependencies are especially important

Rust macros are actually only partially hygienic. • Rust はマルチパラダイムです。たとえば、強力な assert_ne!(prime % i, 0); } } } この機能は IntoIterator トレイトを使用しますが、これはまだ説明していません。 The assert_ne! macro is new here. There are also assert_eq! and assert! macros. These are always checked, while debug-only
