Trait juniper_eager_loading::LoadFrom

pub trait LoadFrom<T>: Sized {
    type Error;

    fn load(ids: &[T], db: &Self::Connection) -> Result<Vec<Self>, Self::Error>;
}

How should associated values actually be loaded?

Normally T will be your id type but for HasMany and HasManyThrough it might also be other values.

If you're using Diesel it is recommend that you use one of the macros to generate implementations.

Associated Types

type Error

The error type. This must match the error set in #[eager_loading(error_type = _)].

type Connection

The connection type required to do the loading. This can be a database connection or maybe a connection an external web service.
