合约领域组件编程规范

// FromPbLimits converts []*pb.ResourceLimit to Limits.

// FromPbLimits converts Limits to []*pb.ResourceLimit.

ValidContractName return error when contractName is not a valid contract name.

StatusError is used when contract fails.

StatusErrorThreshold is the status dividing line for the normal operation of the contract.

StatusOK is used when contract successfully ends.

MaxLimits describes the maximum limit of resources.

ContextConfig define the config of context.

ContractConfig define the config of XuperBridge.

Limits describes the usage or limit of resources.

LogConfig is the log config of node.

NativeConfig contains the two above config.

NativeDockerConfig native contract use docker config.

Response is the result of the contract run.

WasmConfig wasm config.

XVMConfig contains the xvm configuration.

ChainCore is the interface of chain service.

Context define context interface.

CrossQueryState 对XuperBridge暴露对跨链只读合约的操作能力.

Iterator iterates over key/value pairs in key order.

State 抽象了链的状态机接口，合约通过State里面的方法来修改状态。.

StateSandbox 在沙盒环境里面执行状态修改操作，最终生成读写集.

XMState 对XuperBridge暴露对账本的UTXO操作能力.

XMState 对XuperBridge暴露对XModel的读写接口，不同于XMReader， Get和Select方法得到的不是VersionedData，而是[]byte.
