```rust extern crate postgres; extern crate postgresbinarycopy;

use postgres::{Connection, SslMode}; use postgres::types::{Type, ToSql}; use postgresbinarycopy::BinaryCopyReader;

fn main() { let conn = Connection::connect("postgres://postgres@localhost", SslMode::None).unwrap();

conn.execute("CREATE TABLE foo (id INT PRIMARY KEY, bar VARCHAR)", &[])
    .unwrap();

let types = &[Type::Int4, Type::Varchar];
let data: Vec<Box<ToSql>> = vec![Box::new(1i32), Box::new("hello"),
                                 Box::new(2i32), Box::new("world")];
let data = data.iter().map(|v| &**v);
let mut reader = BinaryCopyReader::new(types, data);

let stmt = conn.prepare("COPY foo (id, bar) FROM STDIN (FORMAT binary)").unwrap();
stmt.copy_in(&[], &mut reader).unwrap();

} ```
