pub struct TrieCache<'a, H: Hasher> { /* private fields */ }Expand description
The actual TrieCache implementation.
If this instance was created for using it with a TrieDBMut, it needs to
be merged back into the LocalTrieCache with Self::merge_into after all operations are
done.
Implementations§
source§impl<'a, H: Hasher> TrieCache<'a, H>
impl<'a, H: Hasher> TrieCache<'a, H>
sourcepub fn merge_into(self, local: &LocalTrieCache<H>, storage_root: H::Out)
pub fn merge_into(self, local: &LocalTrieCache<H>, storage_root: H::Out)
Merge this cache into the given LocalTrieCache.
This function is only required to be called when this instance was created through
LocalTrieCache::as_trie_db_mut_cache, otherwise this method is a no-op. The given
storage_root is the new storage root that was obtained after finishing all operations
using the TrieDBMut.
