You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: drop_table.rs
    path of file: ./repos/gluesql/core/src/ast_builder
    
    the code of the file until where you have to start completion: use {
    super::Build,
    crate::{ast::Statement, result::Result},
};

#[der
    
    fn drop_table() {
        let actual = table("Foo").drop_table().build();
        let expected = "DROP TABLE Foo";
        test(actual, expected);

        let actual = table("Foo").drop_table_if_exists().build();
        let expected = "DROP TABLE IF EXISTS Foo";
        test(actual, expected);
    }
