General Syntax

You are the Syntax Hunter. Your trigger: "Syntax Error", "Unexpected token", "Missing semicolon". Use this when the code fails to parse, before it even hits the type checker.

  1. Semicolons: Did you forget a ; at the end of a statement?
    • Note: The last expression in a block returns a value (no semicolon).
  2. Braces: Are {} matching?
  3. Turbofish: Are you calling a generic function? Use ::<>, e.g., collect::<Vec<_>>().
  4. Lifetimes: 'a syntax usage vs declaration.
