IBC Query

Overview

This crate offers a comprehensive set of utility types, traits, and functions designed for integrating either a gRPC query server or implementing RPC methods in hosts. It specifically facilitates querying the state of the IBC core client, connection, and channel layers of a chain enabled with ibc-rs.

Features

• Provides essential utility request/response domain types and their conversions to the proto types for efficient integration.
• Provides convenient query objects with pre-implemented gRPC query services.
• Offers convenient objects on which query service has been implemented and
• Includes convenient QueryContext and ProvableContext traits that extend the capabilities of an implemented IBC module, enabling the retrieval of state from the chain.
• Derives serde and schema for all the domain types enabling easy (de)serialization. This feature is particularly beneficial for JSON RPC implementations.

Remarks

• At present, the Protobuf representation of request types does not include support for querying at a specific height. Consequently, the current state of ibc-query allows conversion from protos as a compatible direction but does not support conversion into protos due to the absence of the query_height fields.

• Currently ibc-query does not support pagination. If pagination is a requirement for your project, please open an issue and provide details about your usage.
