mapLeft<C, L1, L2, R> function

ReaderTaskEither<C, L2, R> Function(ReaderTaskEither<C, L1, R>) mapLeft<C, L1, L2, R>(
  1. L2 f(
    1. L1 a
    )
)

Composes computations in sequence, using the return value from the previous computation.

Implementation

ReaderTaskEither<C, L2, R> Function(ReaderTaskEither<C, L1, R>)
    mapLeft<C, L1, L2, R>(
  L2 Function(L1 a) f,
) =>
        (fa) => ReaderTaskEither(fa.call.compose(TE.mapLeft(f)));
