//! Returns the changes in a block.
//!
//! The `RpcStateChangesInBlockRequest` takes in a [`BlockReference`](https://docs.rs/unc-primitives/0.12.0/unc_primitives/types/enum.BlockReference.html) enum which has multiple variants.
//!
//! ## Example
//!
//! Returns the changes in block for <https://explorer.unc.org/blocks/3Lq3Mtfpc3spH9oF5dXnUzvCBEqjTQwX1yCqKibwzgWR>
//!
//! You can also use the `Finality` and `SyncCheckpoint` variants of [`BlockReference`](https://docs.rs/unc-primitives/0.12.0/unc_primitives/types/enum.BlockReference.html) to return block change details.
//!
//! ```
//! use unc_jsonrpc_client::{methods, JsonRpcClient};
//! use unc_primitives::types::{BlockReference, BlockId};
//!
//! # #[tokio::main]
//! # async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! let client = JsonRpcClient::connect("https://archival-rpc.mainnet.unc.org");
//!
//! let request = methods::EXPERIMENTAL_changes_in_block::RpcStateChangesInBlockRequest {
//!     block_reference: BlockReference::BlockId(BlockId::Height(47988413))
//! };
//!
//! let response = client.call(request).await?;
//!
//! assert!(matches!(
//!     response,
//!     methods::EXPERIMENTAL_changes_in_block::RpcStateChangesInBlockByTypeResponse { .. }
//! ));
//! # Ok(())
//! # }
//! ```
