type Op

type Op int

Op is an integer representing an operation on a configuration key value

	Remove
	// Merge adds an element if not present, do nothing if present

	Toggle
	// Insert adds an element at the position specified by Index
	Insert

func ParseOp

func ParseOp(s string) Op

ParseOp returns an operator from its string representation.

func (Op) Is

func (t Op) Is(op Op) bool

func (Op) MarshalJSON

func (t Op) MarshalJSON() ([]byte, error)

MarshalJSON marshals the enum as a quoted json string

func (Op) String

func (t Op) String() string

func (*Op) UnmarshalJSON

func (t *Op) UnmarshalJSON(b []byte) error

UnmarshalJSON unmashals a quoted json string to the enum value

type T

type T struct {
	Key   key.T
	Op    Op
	Value string
	Index int
}

T defines a parsed key operation

func New

func New(key key.T, op Op, value string, idx int) *T

func Parse

func Parse(s string) *T

func (T) IsZero

func (t T) IsZero() bool

func (T) String

func (t T) String() string
