Cosmos-SDK Plugins

This package contains an extensible plugin system for the Cosmos-SDK. The plugin system leverages the hashicorp/go-plugin system. This system is designed to work over RPC.

Although the go-plugin is built to work over RPC, it is currently only designed to work over a local network.

Pre requisites

For an overview of supported features by the go-plugin system, please see https://github.com/hashicorp/go-plugin. The go-plugin documentation is located here. You can also directly visit any of the links below:

Exposing plugins

To expose plugins to the plugin system, you will need to:

  1. Implement the gRPC message protocol service of the plugin
  2. Build the plugin binary
  3. Export it

Read the plugin documentation in the Streaming Plugins section for examples on how to build a plugin.

Documentation

Overview

Package streaming provides shared data structures and interfaces for communication between the host application and plugins in a streaming context.

	StopNodeOnErr bool
}

Manager is the struct that maintains a list of ABCIListeners and configuration settings.

type StoreKVPair 

type StoreKVPair struct {
	// address defines the address of the account the state changes are coming from.
	// In case of modules you can expect a stringified
	Address []byte `protobuf:"bytes,1,opt,name=address,proto3" json:"address,omitempty"`
	// key defines the key of the address that changed.
