[−][src]Trait sp_trie::TrieConfiguration
Various re-exports from the trie-db
crate.
This trait associates a trie definition with preferred methods.
It also contains own default implementations and can be
used to allow switching implementation.
Provided methods
fn trie_build<DB, I, A, B>(db: &mut DB, input: I) -> <Self::Hash as Hasher>::Out where
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
DB: HashDB<Self::Hash, usize>,
I: IntoIterator<Item = (A, B)>,
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
DB: HashDB<Self::Hash, usize>,
I: IntoIterator<Item = (A, B)>,
Operation to build a trie db from its ordered iterator over its key/values.
fn trie_root<I, A, B>(input: I) -> <Self::Hash as Hasher>::Out where
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
I: IntoIterator<Item = (A, B)>,
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
I: IntoIterator<Item = (A, B)>,
Determines a trie root given its ordered contents, closed form.
fn trie_root_unhashed<I, A, B>(input: I) -> Vec<u8> where
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
I: IntoIterator<Item = (A, B)>,
A: AsRef<[u8]> + Ord,
B: AsRef<[u8]>,
I: IntoIterator<Item = (A, B)>,
Determines a trie root node's data given its ordered contents, closed form.
fn encode_index(input: u32) -> Vec<u8>
Encoding of index as a key (when reusing general trie for indexed trie).
fn ordered_trie_root<I, A>(input: I) -> <Self::Hash as Hasher>::Out where
A: AsRef<[u8]>,
I: IntoIterator<Item = A>,
A: AsRef<[u8]>,
I: IntoIterator<Item = A>,
A trie root formed from the items, with keys attached according to their
compact-encoded index (using parity-codec
crate).
