Rust's borrow checker finally clicked after 2 years of fighting it — what was your breakthrough moment?

Was ready to give up on Rust entirely after months of lifetime annotation hell.

Curious what finally made Rust click for other people who struggled initially.

reading the rustonomicon helped way more than any blog post, understanding WHY the rules exist made them feel less arbitrary

building a linked list (the classic rust rite of passage pain) weirdly taught me more about ownership than any tutorial did

designing with ownership in mind upfront instead of retrofitting is exactly the unlock, 100% agree with op

the compiler error messages have gotten SO much better over the years too, that alone made learning way less painful than when i started
