type ContractReader interface {
services.Service
// GetLatestValue gets the latest value with a certain confidence level that maps to blockchain finality....
// The params argument can be any object which maps a set of generic parameters into chain specific parameters defined in RelayConfig.
// It must encode as an object via [json.Marshal] and [github.com/fxamacker/cbor/v2.Marshal].
// Typically, would be either a struct with field names mapping to arguments, or anonymous map such as `map[string]any{"baz": 42, "test": true}}`
//
// returnVal must [json.Unmarshal] and and [github.com/fxamacker/cbor/v2.Marshal] as an object.
//
// Example use:
// type ProductParams struct {
// ID int `json:"id"`
// }
// type ProductReturn struct {
// Foo string `json:"foo"`
// Bar *big.Int `json:"bar"`
// }
// func do(ctx context.Context, cr ContractReader) (resp ProductReturn, err error) {
// err = cr.GetLatestValue(ctx, "FooContract", "GetProduct", primitives.Finalized, ProductParams{ID:1}, &resp)
// return
// }
//
// Note that implementations should ignore extra fields in params that are not expected in the call to allow easier
// use across chains and contract versions.
// Similarly, when using a struct for returnVal, fields in the return value that are not on-chain will not be set.
GetLatestValue(ctx context.Context, readIdentifier string, confidenceLevel primitives.ConfidenceLevel, params, returnVal any) error
// BatchGetLatestValues batches get latest value calls based on request, which is grouped by contract names that each have a slice of BatchRead.
// BatchGetLatestValuesRequest params and returnVal follow same rules as GetLatestValue params and returnVal arguments, with difference in how response is returned.
// BatchGetLatestValuesResult response is grouped by contract names, which contain read results that maintain the order from the request.
// Contract call errors are returned in the Err field of BatchGetLatestValuesResult.
