Crate node_rpc

source ·
Expand description

A collection of node-specific RPC methods.

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 FRAME pallets are part of it. Therefore all node-runtime-specific RPCs can be placed here or imported from corresponding FRAME RPC definitions.
