var MockMaps map[string]goebpf.Map

MockMaps is list of cross compiled/linked eBPF maps into GO executable This map will contain all eBPF maps defined in eBPF program

Functions

func CleanupAllMockMaps

func CleanupAllMockMaps()

CleanupAllMockMaps re-creates all mock maps Useful for unittests

Types

type MockMap

type MockMap struct {
	Name       string
	Type       goebpf.MapType
	KeySize    int
	ValueSize  int
	MaxEntries int
	// contains filtered or unexported fields
}

MockMap defines eBPF mockmap and implements Map interface

func (m *MockMap) Close() error

Close does nothing - just to implement Map interface

func (*MockMap) Create

func (m *MockMap) Create() error

Create creates MockMap

func (*MockMap) Delete

func (m *MockMap) Delete(ikey interface{}) error

Delete deletes element from mock map Valid only for non array map types
