rust-postgres-cursor

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://jwilm@127.0.0.1/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);
}

} ```
