The Rust borrow checker clicked when I stopped reading it as a style rule and started reading it as a use-after-free detector at compile time. Borrow an element of a Vec, then push to it. The push can reallocate the buffer, so your reference would dangle. C compiles that. Rust won't.

This reframing is the whole unlock. Read the borrow checker as a compile-time use-after-free and data-race detector and the rules stop feeling arbitrary, they become free proofs. Same reason strict types and linters earn their keep on AI-generated code.

The shift: a borrow error isn't the compiler being picky. It's the compiler catching a bug you can't see yet. Read each one as 'this would have dangled' and you stop fighting it. #rustlang

The reframe that worked for me: the borrow checker isn't rejecting code, it's rejecting a question you haven't answered yet, namely who owns this and for how long. Once ownership is explicit the errors mostly fall away.
