	Description = "Indigo's Tendermint Store"

	// DefaultEndpoint is the default Tendermint endpoint.
	DefaultEndpoint = "tcp://127.0.0.1:46657"

	// DefaultWsRetryInterval is the default interval between Tendermint Websocket connection attempts.

Types

type Config

type Config struct {
	// A version string that will be set in the store's information.
	Version string

	// A git commit hash that will be set in the store's information.
	Commit string
}

Config contains configuration options for the store.

type Info

type Info struct {
	Name        string      `json:"name"`
	Description string      `json:"description"`
	TMAppInfo   interface{} `json:"tmAppDescription"`
	Version     string      `json:"version"`
	Commit      string      `json:"commit"`
}

Info is the info returned by GetInfo.
