Struct sea_orm_rocket::Connection

pub struct Connection<'a, D: Database>(_);

A request guard which retrieves a single connection to a Database.

For a database type of Db, a request guard of Connection<Db> retrieves a single connection to Db.

The request guard succeeds if the database was initialized by the Initializer fairing and a connection is available within connect_timeout seconds.

• If the Initializer fairing was not attached, the guard fails with status InternalServerError. A Sentinel guards this condition, and so this type of failure is unlikely to occur. A None error is returned.
• If a connection is not available within connect_timeout seconds or another error occurs, the gaurd fails with status ServiceUnavailable and the error is returned in Some.

Implementations

impl<'a, D: Database> Connection<'a, D>

pub fn into_inner(self) -> &'a <D::Pool as Pool>::Connection

Returns the internal connection value. See the Connection Deref column for the expected type of this value.

Trait Implementations

impl<'r, D: Database> FromRequest<'r> for Connection<'r, D>

type Error = Option<<D::Pool as Pool>::Error>

The associated error to be returned if derivation fails.

fn from_request<'life0, 'async_trait>(
    req: &'r Request<'life0>
) -> Pin<Box<dyn Future<Output = Outcome<Self, Self::Error>> + Send + 'async_trait>> where
    'r: 'async_trait,
    'life0: 'async_trait,
    Self: 'async_trait, 

Derives an instance of Self from the incoming request metadata.

impl<D: Database> Sentinel for Connection<'_, D>

fn abort(rocket: &Rocket<Ignite>) -> bool

Returns true if launch should be aborted and false otherwise.
