type family EndpointsList api where ... Source #

Build a list of endpoints from an API.

type family IsSubAPI sub api :: Constraint where ... Source #

Check whether sub is a sub API of api.

Equations

IsSubAPI sub api = AllIsElem (EndpointsList sub) api 

type family AllIsElem xs api :: Constraint where ... Source #

Check that every element of xs is an endpoint of api.

Equations

AllIsElem '[] api = () 
AllIsElem (x ': xs) api = (IsIn x api, AllIsElem xs api) 

type family MapSub e xs where ... Source #

Apply (e :>) to every API in xs.

Equations

MapSub e '[] = '[] 
MapSub e (x ': xs) = (e :> x) ': MapSub e xs 

type family AppendList xs ys where ... Source #

Append two type-level lists.

Equations

AppendList '[] ys = ys 
AppendList (x ': xs) ys = x ': AppendList xs ys 

type family Or (a :: Constraint) (b :: Constraint) :: Constraint where ... Source #

Equations

Or () b = () 
Or a () = () 

type family IsIn sub api :: Constraint where ... Source #

Equations

IsIn e (a :<|> b) = Or (IsIn e a) (IsIn e b) 
IsIn (e :> a) (e :> b) = IsIn a b 
IsIn e e = () 

type family Elem x xs where ... Source #

Check whether a type is a member of a list of types. This is a type-level analogue of elem.

Equations

Elem x '[] = False 
Elem x (x ': xs) = True 
Elem x (y ': xs) = Elem x xs 

type family Nub xs where ... Source #

Remove duplicates from a type-level list.

Equations

Nub '[] = '[] 
Nub (x ': xs) = x ': Nub (Remove x xs) 

type family Remove x xs where ... Source #

Remove element from a type-level list.

Equations

Remove x '[] = '[] 
Remove x (x ': ys) = Remove x ys 
Remove x (y ': ys) = y ': Remove x ys 

type BodyTypes c api = Nub (BodyTypes' c api) Source #

Extract a list of unique "body" types for a specific content-type from a servant API.

type AddBodyType c cs a as = If (Elem c cs) (a ': as) as Source #

AddBodyType c cs a as adds type a to the list as only if c is in cs.

type family BodyTypes' c api :: [*] where ... Source #

Extract a list of "body" types for a specific content-type from a servant API. To extract unique types see BodyTypes.

Equations

BodyTypes' c (Verb verb b cs (Headers hdrs a)) = AddBodyType c cs a '[] 
BodyTypes' c (Verb verb b cs a) = AddBodyType c cs a '[] 
BodyTypes' c (ReqBody cs a :> api) = AddBodyType c cs a (BodyTypes' c api) 
BodyTypes' c (e :> api) = BodyTypes' c api 
BodyTypes' c (a :<|> b) = AppendList (BodyTypes' c a) (BodyTypes' c b) 
BodyTypes' c api = '[]
