Module `Tezos_alpha_test_helpers.Lwt_result_wrap_syntax`Source

Extends the Lwt_result_syntax with additional utilities for wrapping results produced by the protocol, i.e. Environment.Error_monad.tzresult, to tzresult Lwt.t values used in the tests.

The added utilities are binding operators. They use the same symbols as the ones from Lwt_result_syntax with an added @ character. This character symbolizes the ewrapping of the internal error monad type in a shell error.

val wrap : 
  'a Tezos_protocol_alpha.Environment.Error_monad.tzresult Lwt.t ->
  'a Tezos_base.TzPervasives.tzresult Lwt.t

wrap res maps the result type contained in res to a tzresult value.

  ('a -> 'b Tezos_base.TzPervasives.tzresult Lwt.t) ->

let*@ x = m in f x is equivalent to let* x = wrap m in f x.

Mnemonic: @ "wraps" a protocol error in a shell error.
