class (Pinchable a, Tag a ~ TStruct) => ThriftResult a where

The Result datatype for a Thrift Service Method.

Associated Types

type ResultType a

The Haskell type returned when the Thrift call succeeds.

Methods

unwrap :: a -> IO (ResultType a)

Tries to extract the result from a Thrift call. If the call threw any of the Thrift exceptions declared for this Thrift service method, the corresponding Haskell excpetions is thrown using throwIO.

wrap :: IO (ResultType a) -> IO a

Runs the given computation. If it throws any of the exceptions declared in the Thrift service definition, it is caught and converted to the corresponding Haskell result datatype constructor.
