fn ordered_trie_root<I, A>(input: I) -> <Self::Hash as Hasher>::Outwhere I: IntoIterator<Item = A>, A: AsRef<[u8]>,
A trie root formed from the items, with keys attached according to their
compact-encoded index (using
parity-codec
crate).source§impl<H> TrieLayout for LayoutV1<H>where
H: Hasher,

source§const USE_EXTENSION: bool = false
const USE_EXTENSION: bool = false
If true, the trie will use extension nodes and
no partial in branch, if false the trie will only
use branch and node with partials in both.
source§const ALLOW_EMPTY: bool = true
const ALLOW_EMPTY: bool = true
If true, the trie will allow empty values into
TrieDBMut
source§const MAX_INLINE_VALUE: Option<u32> = _
const MAX_INLINE_VALUE: Option<u32> = _
Threshold above which an external node should be
use to store a node value.
