In the world of alien patterns with a company of a great compiler who warns me about the dangers of this world in every step, here are some of the common pitfalls and puzzlement I’ve had so far. Note that this document is not meant to be a guide for anyone else but myself, excuse my broken language if you are reading this anyway.

<aside> ⚠️

Some examples here are incomplete due to broken copy paste from my main Notion, remind me to fix the missing bits.

Errors as a Teacher

• Dynamic compatibility
• Using std::cmp::max (the trait Ord is not implemented for {float})
• Trait not implemented StdError
• Struggles in printing a variable
• Move occurs because … does not implement Copy trait
• Stack overflow! (also where GPT failed)
• I literally declared a variable as mut how come compiler sees it as immutable?
• Missing lifetime specifier
• Cannot move out of self.*** which is behind a mutable reference
• The size for values of type (dyn MyInterestingTrait + ‘static) cannot be known at compilation time
