|
|
//! Since `substrate` core functionality makes no assumptions
|
|
//! about the modules used inside the runtime, so do
|
|
//! RPC methods defined in `sc-rpc` crate.
|
|
//! It means that `client/rpc` can't have any methods that
|
|
//! need some strong assumptions about the particular runtime.
|
|
//!
|
|
//! The RPCs available in this crate however can make some assumptions
|
|
//! about how the runtime is constructed and what `SRML` modules
|
|
//! are part of it. Therefore all node-runtime-specific RPCs can
|
|
//! be placed here or imported from corresponding `SRML` RPC definitions.
