pattern (::&) :: Extensible a => a es' -> Chain es -> a es infix 6 Source #
A pattern synonym to separate the head of a struct chain from the
tail, use in conjunction with :&
to extract several members.
Head{..} ::& () <- returningNoTail a b c -- Equivalent to Head{..} <- returningNoTail @'[] a b c
Head{..} ::& Foo{..} :& Bar{..} :& () <- returningWithTail a b c
