I'm using Dagger @Binds to binding the interface to implementation.

I have genric mapper which transform one object to other.

interface DataMapper<T, R> {
     fun transform(from: T): R
 }

So I have couple of Data mapper in each use case layer .

Let's I have something like this

class AccountDataMapper @Inject constructor():
DataMapper<Account,Result<Account>>{

override fun transform(account : Account){

}


}


How can I bind this. I have many mapper in the like Login Mapper,User mapper.

When I use thr binder it's complaining that

@Binds method parameter type must be assignable to the return type

@Binds
abstract fun bindAccountMapper(mapper AccountDataMapper) : DataMapper<Account,Result<Account>>


Thanks in advance

Looks fine, maybe check your imports? You might have imported wrong Result<> class
