Implementations

impl ToolsDb

pub fn fairing() -> impl Fairing

Returns a fairing that initializes the associated database connection pool.

pub async fn get_one<'_>(__rocket: &'_ Rocket) -> Option<Self>

Retrieves a connection of type Self from the rocket instance. Returns Some as long as Self::fairing() has been attached.

pub async fn run<F, R, '_>(&'_ self, __f: F) -> R where
    F: FnOnce(&mut MysqlConnection) -> R + Send + 'static,
    R: Send + 'static, 

Runs the provided closure on a thread from a threadpool. The closure will be passed an &mut r2d2::PooledConnection. .awaiting the return value of this function yields the value returned by the closure.
