Synopsis

jsonString :: JSValue -> Result String
jsonInt :: Integral n => JSValue -> Result n
jsonObject :: JSValue -> Result [(String, JSValue)]
jsonField :: JSON a => String -> [(String, JSValue)] -> Result a
jsonBool :: JSValue -> Result Bool
jsonIsTrue :: String -> [(String, JSValue)] -> Result Bool

Documentation

jsonString :: JSValue -> Result String Source #

jsonInt :: Integral n => JSValue -> Result n Source #

jsonObject :: JSValue -> Result [(String, JSValue)] Source #

jsonField :: JSON a => String -> [(String, JSValue)] -> Result a Source #

Extract a field as a value of type a. If the field does not exist or cannot be parsed as type a, fail.

jsonBool :: JSValue -> Result Bool Source #

jsonIsTrue :: String -> [(String, JSValue)] -> Result Bool Source #

True when the field is defined and is true. Otherwise, False.
