Trait PartialStorageInfoTrait
pub trait PartialStorageInfoTrait {
// Required method
fn partial_storage_info() -> Vec<StorageInfo>;
}Expand description
Similar to StorageInfoTrait, a trait to give partial information about storage.
This is useful when a type can give some partial information with its generic parameter doesn’t implement some bounds.
Required Methods§
fn partial_storage_info() -> Vec<StorageInfo>
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
Implementors§
impl<Prefix, Hasher1, Hasher2, Key1, Key2, Value, QueryKind, OnEmpty, MaxValues> PartialStorageInfoTrait for StorageDoubleMap<Prefix, Hasher1, Key1, Hasher2, Key2, Value, QueryKind, OnEmpty, MaxValues>where
Prefix: StorageInstance,
Hasher1: StorageHasher,
Hasher2: StorageHasher,
Key1: FullCodec,
Key2: FullCodec,
Value: FullCodec,
QueryKind: QueryKindTrait<Value, OnEmpty>,
OnEmpty: Get<<QueryKind as QueryKindTrait<Value, OnEmpty>>::Query> + 'static,
MaxValues: Get<Option<u32>>,
It doesn’t require to implement MaxEncodedLen and give no information for max_size.
