I have to use std::iter::FromIterator; in code calling the api_operation macro

[Ploppz]

I'm just starting to wrap my API in this library. I got this error

error[E0599]: no function or associated item named `from_iter` found for struct `BTreeMap` in the current scope

     = note: this error originates in the attribute macro `api_operation` (in Nightly builds, run with -Z macro-backtrace for more info)
help: trait `FromIterator` which provides `from_iter` is implemented but not in scope; perhaps you want to import it

1    + use std::iter::FromIterator;
     |

Just want to suggest to use fully qualified syntax to use FromIterator::from_iter for example so that library users don't have to import that trait.

Hi,

Sorry for the delay, I'm having a look.

Is it possible to provide a minimal reproduction example please ? I'm currently unable to reproduce.
