Times and logs queries executed by diesel

Diesel Logger

Let's say you use Diesel like this:

let conn = SqliteConnection::establish("example.sqlite").unwrap();
// some commands that read/write from the conn database

You can change this to

let conn = SqliteConnection::establish("example.sqlite").unwrap();
let conn = LoggingConnection::new(conn);
// some commands that read/write from the conn database

to log everything. This produces a debug log on every query, an info on queries that take longer than 1 second, and a warning on queries that take longer than 5 seconds.

Example

$ cd example
$ cargo run
2022-06-06T22:42:29.266Z DEBUG [diesel_logger] Query ran in 4.9 ms: CREATE TABLE IF NOT EXISTS posts (id INTEGER, title TEXT, body TEXT, published BOOL);
2022-06-06T22:42:29.270Z DEBUG [diesel_logger] Query ran in 3.7 ms: INSERT INTO `posts` (`title`, `body`) VALUES (?, ?) -- binds: ["mytitle", "mybody"]
