Trait fuel_storage::StorageAsRef

pub trait StorageAsRef {
    fn storage<Type>(&self) -> StorageRef<'_, Self, Type>
   where
        Type: Mappable,
    { ... }
}

Helper trait for StorageInspect to provide user-friendly API to retrieve storage as reference.

Example

use fuel_storage::{Mappable, StorageInspect, StorageAsRef};

pub struct Contracts;

impl Mappable for Contracts {
    type Key = [u8; 32];
    type SetValue = [u8];
    type GetValue = Vec<u8>;
}

pub struct Balances;

impl Mappable for Balances {
    type Key = u128;
    type SetValue = u64;
    type GetValue = u64;
}

pub trait Logic: StorageInspect<Contracts> + StorageInspect<Balances> {
    fn run(&self) {
        // You can specify which storage do you want to call with `storage::<Type>()`
        let _ = self.storage::<Contracts>().get(&[0; 32]);
        let _ = self.storage::<Balances>().get(&123);
    }
}
