//! Solidity ABI bindings for the contracts Tron facilitators call into.
//!
//! These generate [`alloy_sol_types::SolCall`] encoders/decoders (function
//! selector + calldata), used to build the `data` field of a TronGrid
//! `triggersmartcontract` request. This is distinct from the TIP-712
//! *struct* definitions in [`crate::exact::types`], which are used for
//! typed-data signing rather than calldata encoding.
