func Install(cacheDir string) (string, error)

func Version ¶

func Version() (string, error)

Version is used to get the version of the protoc-gen-go plugin. For older versions, protoc-gen-go does not support version fetching, so if protoc-gen-go --version is executed, it will cause the process to block, so it is controlled by a timer to prevent the older version process from blocking.
