I got a bug report on Diesel from someone who has a database column called bool. This lead to us attempting to generate the following code:

pub struct bool;

impl QueryId for bool {
    type QueryId = Self;
    const HAS_STATIC_QUERY_ID: bool = true;
}

which causes a type mismatch because their struct is shadowing the primitive. I'd like to change the generated code to be const HAS_STATIC_QUERY_ID: ::std::bool, which is the path that the rustdoc for libstd indicates it should be, but the type doesn't exist there, or anywhere else I can find. I would assume the same issue exists for str, char, and all the numeric types.
