Most userland implementations of custom ReadableStream instances do not typically bother with all the ceremony required to correctly implement both default and BYOB read support in a single stream – and for good reason. It's difficult to get right and most of the time consuming code is typically going to fallback on the default read path. The example below shows what a "correct" implementation would need to do. It's big, complex, and error prone, and not a level of complexity that the typical developer really wants to have to deal with:

ballin#One night — after a glass of wine — I had another idea: one modern trick with ASCII art is the use of Braille unicode characters to allow for very high detail. That reminded me of ball physics simulations, so what about building a full physics simulator also in the terminal? So I asked Opus 4.5 to create a terminal physics simulator with the rapier 2D physics engine and a detailed explanation of the Braille character trick: this time Opus did better and completed it in one-shot, so I spent more time making it colorful and fun. I pessimistically thought the engine would only be able to handle a few hundred balls: instead, the Rust codebase can handle over 10,000 logical balls!，推荐阅读爱思助手下载最新版本获取更多信息
