## Fields

These are Serialization Fields (`sf`) [defined in rippled's SField.cpp](https://github.com/ripple/rippled/blob/develop/src/ripple/protocol/impl/SField.cpp).

### Key

The key is the string defined in the rippled source code, such as "LedgerEntry", "Transaction", etc.

### nth

nth is the `index` used to make an [`SField` field code](https://github.com/ripple/rippled/blob/eaff9a0e6aec0ad077f118501791c7684debcfd5/src/ripple/protocol/SField.h#L95-L98).

### isVLEncoded

If true, the field is Variable Length encoded. 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](https://github.com/ripple/rippled/blob/eaff9a0e6aec0ad077f118501791c7684debcfd5/src/ripple/protocol/impl/SField.cpp#L71-L78) or if they are not an SField.

### isSigningField

True unless the field is [specified with `SField::notSigning`](https://github.com/ripple/rippled/blob/eaff9a0e6aec0ad077f118501791c7684debcfd5/src/ripple/protocol/impl/SField.cpp#L198).
