Types

type Key

type Key struct {
	// contains filtered or unexported fields
}

Key is the index into the prog array map. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapKey

func (*Key) DeepCopy added in v1.8.0

func (in *Key) DeepCopy() *Key

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Key.

func (*Key) DeepCopyInto added in v1.8.0

func (in *Key) DeepCopyInto(out *Key)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*Key) DeepCopyMapKey added in v1.8.0

func (in *Key) DeepCopyMapKey() bpf.MapKey

DeepCopyMapKey is an autogenerated deepcopy function, copying the receiver, creating a new bpf.MapKey.

func (*Key) GetKeyPtr added in v1.8.0

func (k *Key) GetKeyPtr() unsafe.Pointer

GetKeyPtr returns the unsafe pointer to the BPF key

func (Key) NewValue added in v1.8.0

func (k Key) NewValue() bpf.MapValue

NewValue returns a new empty instance of the structure representing the BPF map value.

func (*Key) String

func (k *Key) String() string

String converts the key into a human readable string format.

type Value

type Value struct {
	// contains filtered or unexported fields
}

Value is the program ID in the prog array map. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapValue

func (*Value) DeepCopy added in v1.8.0

func (in *Value) DeepCopy() *Value
