Re-Export the derive macro from the dlopen crate
Currently, to use dlopen, the user needs 2 dependencies, one for the derive macro and one for the library itself
dlopen = "0.1"
dlopen_derive = "0.1"
as well as this extra dependency, crates also need to #[macro_use]
the derive crate in order to use the macro
#[macro_use]
extern crate dlopen_derive;
This could be remedied by putting the above statement in the dlopen crate itself, much like how serde re-exports the Serialize and Deserialize dervive macros (https://github.com/serde-rs/serde/blob/master/serde/src/lib.rs#L278-L289). So the user would only need to use the trait and it would also import the macro under the same name.
It might also be possible to do this in the wrapper
module rather than the crate root so that the user importing the trait use dlopen::wrapper::WrapperApi
they would also import the derive macro of that name.
dlopen could also gate it behind a derive
feature much like serde does if the macros are meant to be optional
