Read the signature

  • The text after the name is the type checked by Pudu.
  • Read arrows from left to right: inputs come first, and the final type is returned.
  • & borrows a value for this call instead of moving or copying it.
  • Names inside [ ] are type arguments, such as the item type held by a collection.
  • Result makes success and recoverable failure part of the function's type.
