Instances

Exception CppException

Defined in Language.C.Inline.Cpp.Exception

Methods

toException :: CppException -> SomeException

fromException :: SomeException -> Maybe CppException

displayException :: CppException -> String

Show CppException

Defined in Language.C.Inline.Cpp.Exception

Methods

showsPrec :: Int -> CppException -> ShowS

show :: CppException -> String

showList :: [CppException] -> ShowS

type CppExceptionPtr = ForeignPtr AbstractCppExceptionPtr

toSomeException :: CppException -> SomeException

Like toException but unwrap CppHaskellException

throwBlock :: QuasiQuoter

Like tryBlock, but will throw unwrapped CppHaskellExceptions or other CppExceptions rather than returning them in an Either

tryBlock :: QuasiQuoter

Similar to block, but C++ exceptions will be caught and the result is (Either CppException value). The return type must be void or constructible with {}. Using this will automatically include exception, cstring and cstdlib.

catchBlock :: QuasiQuoter

Variant of throwBlock for blocks which return void.
