func (*BinaryMapKey) NewValue

func (k *BinaryMapKey) NewValue() bpf.MapValue

func (*BinaryMapKey) String

func (k *BinaryMapKey) String() string

type BinaryMapValue

type BinaryMapValue struct {
	Id uint32
}

func (*BinaryMapValue) DeepCopyMapValue

func (v *BinaryMapValue) DeepCopyMapValue() bpf.MapValue

func (*BinaryMapValue) GetValuePtr

func (v *BinaryMapValue) GetValuePtr() unsafe.Pointer

type GenericTracepointConf

type GenericTracepointConf = v1alpha1.TracepointSpec

GenericTracepointConf is the configuration for a generic tracepoint. This is a caller-defined structure that configures a tracepoint.

type GenericTracepointConfArg

type GenericTracepointConfArg v1alpha1.KProbeArg

GenericTracepointConfArg represents an argument of a generic tracepoint

This points to the index of the argument. (Another option might be to specify this by name)
