Enum ContractExecutableRef 

pub enum ContractExecutableRef {
    Wasm(Hash),
    StellarAsset,
    ExternalRef(ExternalExecutableRef),
}

A contract’s executable as recorded in its ContractInstance ledger entry.

Protocol 28 (CAP-0085) widened the ContractExecutable union beyond an inline Wasm hash, so “the contract’s code” is no longer always a single Hash. This mirrors the XDR union faithfully; callers that need the actual code resolve the referenced entry through the RPC layer.

Variants

Wasm(Hash)

CONTRACT_EXECUTABLE_WASM: the instance’s own Wasm hash.

StellarAsset

CONTRACT_EXECUTABLE_STELLAR_ASSET: a Stellar Asset Contract. This is protocol-defined code with no Wasm artifact of its own — there is no hash to report and nothing to download.

ExternalRef(ExternalExecutableRef)

CONTRACT_EXECUTABLE_EXTERNAL_REF (CAP-0085): the instance holds no code; it references an entry owned by another contract.

Implementations

impl ContractExecutableRef

pub fn kind(&self) -> &'static str

Stable lowercase label (wasm, stellar_asset, external_ref).

pub fn executable_tag_key(&self) -> Option<&ExternalExecutableRef>

The ledger key of the owner’s executable entry, for resolution.

CAP-0085 keys this entry with SCV_EXECUTABLE_TAG and stores it as Persistent contract data (the host rejects the Temporary and Instance durabilities for such entries).
