1//! A collection of node-specific RPC methods.2//! Substrate provides the `sc-rpc` crate, which defines the core RPC layer3//! used by Substrate nodes. This file extends those RPC definitions with4//! capabilities that are specific to this project's runtime configuration.56use std::sync::Arc;7use core::marker::PhantomData;89use
