Definitions
Types
These are the types associated with a given Serialization Field. Each type has an arbitrary type_code, with lower codes sorting first.
Ledger Entry Types
Each ledger's state tree contain ledger objects, which represent all settings, balances, and relationships in the shared ledger.
Fields
These are Serialization Fields (sf) defined in rippled's SField.cpp. Fields with undefined values are omitted before encoding.
Key
The key is the string defined in the rippled source code, such as "LedgerEntry", "Transaction", etc.
nth
nth is the sort code, meaning "nth of type." It is is combined with the type code in order to construct the Field ID of this field. The Field ID is only used for sorting the fields. Since there are multiple fields with the same data type, the nth is used to deterministically order each field among other fields of the same data type.
Each field has a Field ID, which is used to sort fields that have the same type as one another with lower codes sorting first.
For example, the Account field has sort code (nth) 1, so it comes before the Destination field which has sort code 3.
Sort code numbers are reused for fields of different types, but different fields of the same type never have the same sort code. When you combine the type code with the sort code, you get the field's unique Field ID.
The unique Field ID is prefixed before the field in the final serialized blob. The size of the Field ID is one to three bytes depending on the type code and the field codes it combines.
isVLEncoded
If true, the field is Variable Length encoded and length-prefixed. The variable-length encoded fields are STI_VL/Blob, STI_ACCOUNT/AccountID, and STI_VECTOR256/Vector256.
isSerialized
Fields are serialized if they are not one of these or if they are not an SField.

isSigningField
True unless the field is specified with SField::notSigning.
