Function encode_storage_key_suffix_with_info_to 

pub fn encode_storage_key_suffix_with_info_to<Resolver, Keys>(
    keys: Keys,
    storage_info: &StorageInfo<'_, <Resolver as TypeResolver>::TypeId>,
    type_resolver: &Resolver,
    out: &mut Vec<u8>,
) -> Result<(), StorageKeyEncodeError>
where
    Keys: IntoEncodableValues,
    Resolver: TypeResolver,
    <Resolver as TypeResolver>::TypeId: Clone + Debug,

Encode the end part of a storage key (ie everything except for the prefix that can be encoded via encode_storage_key_prefix) for a given pallet and storage entry and a set of keys that are each able to be encoded via scale_encode::EncodeAsType.

This is the same as encode_storage_key_suffix_to, but is instead handed storage info that has been pre-computed via StorageTypeInfo::storage_info. This avoids having to retrieve this information multiple times if you’d like to encode many key suffixes for the same storage entry.

Prefer encode_storage_key_with_info_to if you need to encode the entire storage key at once and not just the suffix.
