type NiceMD

type NiceMD metadata.MD

NiceMD is a convenience wrapper definiting extra functions on the metadata.

func ExtractIncoming
func ExtractIncoming(ctx context.Context) NiceMD

ExtractIncoming extracts an inbound metadata from the server-side context.

This function always returns a NiceMD wrapper of the metadata.MD, in case the context doesn't have metadata it returns a new empty NiceMD.

func ExtractOutgoing
func ExtractOutgoing(ctx context.Context) NiceMD

ExtractOutgoing extracts an outbound metadata from the client-side context.

This function always returns a NiceMD wrapper of the metadata.MD, in case the context doesn't have metadata it returns a new empty NiceMD.

func (NiceMD) Add
func (m NiceMD) Add(key string, value string) NiceMD

Add retrieves a single value from the metadata.

It works analogously to http.Header.Add, as it appends to any existing values associated with key.

The function is binary-key safe.

func (NiceMD) Clone
func (m NiceMD) Clone(copiedKeys ...string) NiceMD

Clone performs a deep copy of the metadata.MD.

You can specify the lower-case copiedKeys to only copy certain whitelisted keys. If no keys are explicitly whitelisted all keys get copied.

func (NiceMD) Del
func (m NiceMD) Del(key string) NiceMD
func (NiceMD) Get
func (m NiceMD) Get(key string) string

Get retrieves a single value from the metadata.

It works analogously to http.Header.Get, returning the first value if there are many set. If the value is not set, an empty string is returned.

The function is binary-key safe.

func (NiceMD) Set
func (m NiceMD) Set(key string, value string) NiceMD

Set sets the given value in a metadata.

It works analogously to http.Header.Set, overwriting all previous metadata values.

The function is binary-key safe.

func (NiceMD) ToIncoming
func (m NiceMD) ToIncoming(ctx context.Context) context.Context

ToIncoming sets the given NiceMD as a server-side context for dispatching.

This is mostly useful in ServerInterceptors..

func (NiceMD) ToOutgoing
func (m NiceMD) ToOutgoing(ctx context.Context) context.Context

ToOutgoing sets the given NiceMD as a client-side context for dispatching.
