Type Alias Bar

pub type Bar<T: Config> = StorageMap<_GeneratedPrefixForStorageBar<T>, Blake2_128Concat, T::AccountId, T::Balance>;

The Hasher requirement is skipped by dev_mode. So, second parameter can be _ and Blake2_128Concat is used as a default. When the dev_mode is removed, we would need to specify the hasher like so: pub type Bar<T: Config> = StorageMap<_, Blake2_128Concat, T::AccountId, T::Balance>;.

Storage type is [StorageMap] with key type T :: AccountId and value type T :: Balance.

Aliased Type

struct Bar<T: Config>(/* private fields */);
