Dynamically Loading values into Select Statements

[acycliczebra]

I want to load values dynamically into my select statement. Is this possible in Diesel?

I would Ideally like to be able to pass a vector that I can dynamically generate, and get back as dynamically typed values in return.

Here's a simplified version of the problem:

let columns = binding_at_runtime(); // at runtime, either returns ("a",), ("b",), ("a", "b") or ("b", "a"), or ("a", "b", "c"), or ("a", "c", "b"), etc.
let data: Vec<Vec<Value>> = my_table.select(columns).load(&conn)?;

Thanks everyone!

How would Value looks like in that case?
