Struct Contract 

pub struct Contract { /* private fields */ }

Bound contract for making eth_call.

PHASE C BLOCKER: call() and try_call() are stubs returning fake values. They need graph-node’s EthereumAdapter (or the HostFn interface) to make real eth_call RPC requests. This requires:

• Access to the chain adapter via HostFn[] passed through MappingContext
• The block pointer for the call context
• ABI encoding/decoding of function args and return values

Until Phase C wiring, any handler using Contract.call/try_call will get wrong results. The transpiler’s call-graph analysis already marks these handlers as unsupported (WASM fallback), so stubs are never hit in practice.

Tests for contract calls are also blocked on Phase C — they require a running Ethereum node or mock adapter.

Implementations

impl Contract

pub fn bind(contract_type: &str, address: &Address) -> Self

pub fn call(&self, _method: &str, _args: &[DecodedParam]) -> DecodedParam

STUB: Always returns zero. Phase C will wire to EthereumAdapter via HostFn.

pub fn try_call(&self, _method: &str, _args: &[DecodedParam]) -> CallResult

STUB: Always returns reverted. Phase C will wire to EthereumAdapter via HostFn.
