Functions

func Clone

func Clone(parent context.Context) context.Context

Clone copy the origin mosn value context(if it is), and return new one

func Get

func Get(ctx context.Context, key types.ContextKey) interface{}

func WithValue

func WithValue(parent context.Context, key types.ContextKey, value interface{}) context.Context

WithValue add the given key-value pair into the existed value context, or create a new value context contains the pair. This Function should not be used along the official context.WithValue !! The following context topology will leads to existed pair {'foo':'bar'} NOT FOUND, cause recursive lookup for key-type=ContextKey is not supported by mosn.valueCtx.

topology: context.Background -> mosn.valueCtx{'foo':'bar'} -> context.valueCtx -> mosn.valueCtx{'hmm':'haa'}
