Trait frame_support::storage::StorageAppend
source · pub trait StorageAppend<Item: Encode>: Sealed { }Expand description
Marker trait that will be implemented for types that support the storage::append api.
This trait is sealed.
Implementations on Foreign Types§
impl<T: Encode> StorageAppend<T> for BTreeSet<T>
impl StorageAppend<DigestItem> for Digest
We abuse the fact that SCALE does not put any marker into the encoding, i.e. we only encode the
internal vec and we can append to this vec. We have a test that ensures that if the Digest
format ever changes, we need to remove this here.
