Functions ¶

func DecodeKeyValue ¶

func DecodeKeyValue(k, v string) (string, string, error)

DecodeKeyValue returns the original key and value corresponding to the encoded data in k, v.

func NewContext ¶

func NewContext(ctx context.Context, md MD) context.Context

NewContext creates a new context with md attached.

Types ¶

type MD ¶

type MD map[string][]string

MD is a mapping from metadata keys to values. Users should use the following two convenience functions New and Pairs to generate MD.

func FromContext ¶

func FromContext(ctx context.Context) (md MD, ok bool)

FromContext returns the MD in ctx if it exists.

func New ¶

func New(m map[string]string) MD

New creates a MD from given key-value map.

func Pairs ¶

func Pairs(kv ...string) MD

Pairs returns an MD formed by the mapping of key, value ... Pairs panics if len(kv) is odd.

func (MD) Copy ¶

func (md MD) Copy() MD

Copy returns a copy of md.

func (MD) Len ¶

func (md MD) Len() int

Len returns the number of items in md.
