Enum Unmapped 

pub enum Unmapped {}

The T of a generated SField constant whose XRPL wire type has no Rust mapping yet (VECTOR256, PATHSET, XCHAIN_BRIDGE, …).

The constant still exists, so its field code stays available to callers that only need the code – sfield::Indexes.into() for a raw le_field read, or a Locator path segment. What it can’t do is decode: Unmapped deliberately implements neither FromCurrentTx nor FromLedger, so current_tx::get_field(sfield::Indexes) is a compile error rather than a read that type-checks and then fails at runtime.

This is an uninhabited enum – there is no value of this type, only the name, which is all a PhantomData type parameter needs.

Wiring up a real type for one of these wire types (add it to typeMap in tools/sfieldTypeMap.js, implement FieldDecoder, regenerate) turns every affected constant into the real type, and any code that was reading it raw keeps compiling.
