Types

type EbpfMap

type EbpfMap interface {
	// CreateAndPinArrayMap create map with default set of key/value data
	// only supports map of "array" type, pinning of "pingByName" type
	// dir is the base path to pin map
	// $dir/$name is the path to pin map
	// If the map already existed,
	CreateAndPinArrayMap(dir, name string, defaultKV []ebpf.MapKV) (err error)
	// UnpinArrayMap removes the persisted state for the map from the BPF virtual filesystem
	UnpinArrayMap(pinPath string) (err error)
	// LookUpMapValue looks up the value of the key
	LookUpMapValue(pinPath string, key, value interface{}) (err error)
	// UpdateMapValue updates the value of the key
	UpdateMapValue(pinPath string, key, value interface{}) (err error)
}
