A hammer you can only hold by the handle
summary
Claim: Rust’s type system enforces concrete API invariants at compile time. It uses affine types and non-Clone structs as tokens so operations consume values, encodes state machines as distinct types (empty vs closed envelope), and implements Drop flushing for guaranteed cleanup. Three real examples show errors that used to be runtime or logical become compile errors (double-use, empty-send, forgotten flush), and the encoded APIs compile and prevent the bad behaviors.
