Types

type ConfigProvider

type ConfigProvider func(varName string) (string, error)

ConfigProvider returns the value of the supplied variable as a JSON string. A config provider is used at the time of data source creation to allow the data source to be correctly configured.

type DataSource

type DataSource interface {
	// Name returns the name of this data source and is used to determine if
	// an import path should be processed by the data source importer.
	Name() string
	// Resolve resolves the absolute path defined for the data source to a string.
	Resolve(path string) (string, error)
}

DataSource is a named delegate that can resolve import paths. Multiple VMs may access a single instance of a data source. Thus, data source implementations must be safe for concurrent use.
