====================

A cursor type for use with PostgreSQL.

## Example

```rust

extern crate postgres;

extern crate postgres_cursor;

use postgres::{Client, NoTls};

use postgres_cursor::Cursor;

// First, establish a connection with postgres

let mut client = Client::connect("postgres://[email protected]/foo", NoTls)

    .expect("connect");

// Build the cursor

let mut cursor = Cursor::build(&mut client)

    // Batch size determines rows returned in each FETCH call

    .batch_size(10)

    // Query is the statement to build a cursor for

    .query("SELECT id FROM products")

    // Finalize turns this builder into a cursor

    .finalize()

    .expect("cursor creation succeeded");

// Iterate over batches of rows

for result in &mut cursor {

    // Each item returned from the iterator is a Result, postgres::Error>.

    // This is because each call to `next()` makes a query

    // to the database.

    let rows = result.unwrap();

    // After handling errors, rows returned in this iteration

    // can be iterated over.

    for row in &rows {

        println!("{:?}", row);

    }

}

```
