Connection example

[victrcodes]

What exactly is r2d2_foodb::FooConnectionManager in the example and is there a source code of it somewhere? I tried using something like this:

let config = r2d2::Config::default();
let manager = r2d2::ConnectionManager::new("postgres://postgres:postgres@localhost/test");
let error_handler = Box::new(r2d2::LoggingErrorHandler);
let pool = Arc::new(r2d2::Pool::new(config, manager, error_handler).unwrap());

but it throws an error

src/main.rs:125:16: 125:44 error: the value of the associated type `Error` (from the trait `r2d2::ConnectionManager`) must be specified [E0191]
src/main.rs:125     let manager = r2d2::ConnectionManager::new(DB_URI);

r2d2_foodb doesn't exist - it's an imaginary crate used for that example.

ConnectionManager is a trait - you can't instantiate it directly. See r2d2_postgres for postgres support as well as a code example.

Sorry, my bad, just got confused by these similar looking repos. Thanks.
