changes_in_block.rs

1//! Returns the changes in a block.
2//!
3//! 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.
4//!
5//! ## Example
6//!
7//! Returns the changes in block for <https://explorer.unc.org/blocks/3Lq3Mtfpc3spH9oF5dXnUzvCBEqjTQwX1yCqKibwzgWR>
8//!
9//! 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.
10//!
