with_prefix! Making the module public

[elpiel]

On a few occasions we have the same struct with the same prefix used in our applications. Currently the with_prefix creates a private module for serialize/deserialize and we have to do a hack in order to use the same prefix in other places and applications.

I'm opening this issue to see how this could be improved in future version.

// re-export the prefix module!
pub mod prefix_active {
    use serde_with::with_prefix;

    pub use prefix_active::*;

    with_prefix!(prefix_active "active_");
}

PS: Thank you all very much for creating and maintaining this crate!

with_prefix! extends to a simple module (source). Would it be enough for you to extend the syntax with an optional visibility qualifier in front of the module name? Something like this. The default would still be private (i.e., pub(self)).

with_prefix!(prefix_active "active_");                   // => mod {...}
with_prefix!(pub prefix_active "active_");               // => pub mod {...}
with_prefix!(pub(crate) prefix_active "active_");        // => pub(crate) mod {...}
with_prefix!(pub(in other_mod) prefix_active "active_"); // => pub(in other_mod) mod {...}

I will try to make time and do the changes 😋

Thank you :) The change shouldn't be too complicated. You can see how it works for serde_conv! 84aecca
1-2 sentences in the documentation about this should be enough.
