8. addHeader :: forall (h :: Symbol) v orig new . AddHeader '[Optional, Strict] h v orig new => v -> orig -> new

   servant	Servant.API

   addHeader adds a header to a response. Note that it changes the type of the value in the following ways:

   1. A simple value is wrapped in "Headers '[hdr]":

   >>> let example0 = addHeader 5 "hi" :: Headers '[Header "someheader" Int] String;
   
   >>> getHeaders example0
   [("someheader","5")]
   

   1. A value that already has a header has its new header *prepended* to the existing list:

   >>> let example1 = addHeader 5 "hi" :: Headers '[Header "someheader" Int] String;
   
   >>> let example2 = addHeader True example1 :: Headers '[Header "1st" Bool, Header "someheader" Int] String
   
   >>> getHeaders example2
   [("1st","true"),("someheader","5")]
   

   Note that while in your handlers type annotations are not required, since the type can be inferred from the API type, in other cases you may find yourself needing to add annotations.

9. addHeader' :: forall (mods :: [Type]) (h :: Symbol) v orig new . AddHeader mods h v orig new => v -> orig -> new

   servant	Servant.API

   Same as addHeader but works with Header', so it's possible to use any mods.

10. buildHeadersTo :: BuildHeadersTo hs => [Header] -> HList hs

    servant	Servant.API

    No documentation available.
