技术咨询：m与rx是否存在差异？二者在文档中可互换，含意图层面吗？

Great catch—this is one of those terminology quirks that trips up a lot of folks because official docs do swap m and rx pretty freely. Let’s break down the intent-based differences that are often hidden behind that interchangeable use:

• rx is all about reaction
  When docs use rx, they’re usually highlighting that the code in question is meant to react to something—an event, a state update, an external input, you name it. Think of it as the "something happens → this runs" flow. For example, an rx-labeled handler might trigger when a user submits a form, or when a data stream emits a new value. The core intent here is responsiveness to external stimuli.

• m focuses on initiation
  m, by contrast, frames code as a discrete action or message that starts a process. It’s less about reacting to something and more about "here’s a thing you can call to make X happen." An m-tagged function might be a command that sends data to an API, or a method that initializes a component—something you invoke intentionally, not something that fires in response to a trigger.

Now, to be clear: many docs use these terms interchangeably because the end result (executing code) looks similar. But if you’re trying to align with the implicit intent behind each term:

• Use rx when describing code that responds to events or changes
• Reach for m when talking about code that initiates an action or process
