## Structs

- [ConfirmedNote](/aztec-nr-api/mainnet/noir_aztec/note/struct.ConfirmedNote.md): A note that has been confirmed to exist.
- [HintedNote](/aztec-nr-api/mainnet/noir_aztec/note/struct.HintedNote.md): A hint for a note that might exist.
- [MaybeNoteMessage](/aztec-nr-api/mainnet/noir_aztec/note/struct.MaybeNoteMessage.md): Same as [`NoteMessage`](/aztec-nr-api/mainnet/noir_aztec/note/struct.NoteMessage.md), except this type also handles the possibility where the note may not have been actually created depending on runtime conditions (e.g. a token transfer change note is not created if there is no change).
- [NoteMessage](/aztec-nr-api/mainnet/noir_aztec/note/struct.NoteMessage.md): A message with information about a note that was created in the current contract call. This message **MUST** be delivered to a recipient in order to not lose the private note information.
