Struct OverlayFSDriver

pub struct OverlayFSDriver;

Driver for creating OverlayFS instances

This driver implements the FileSystemDriver trait to allow OverlayFS to be created through the standard filesystem driver infrastructure. Currently, OverlayFS instances are typically created programmatically rather than through driver parameters due to the complexity of specifying multiple layer mount points.
