Trait Implementations

impl Clone for TrieStream[+]

[+] Show hidden undocumented items

fn clone(&self) -> TrieStream[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Default for TrieStream[+]

[+] Show hidden undocumented items

fn default() -> TrieStream[−]

impl TrieStream for TrieStream[+]

[+] Show hidden undocumented items

fn new() -> Self[−]

Construct a new TrieStream

fn append_empty_data(&mut self)[−]

Append an Empty node

fn append_leaf(&mut self, key: &[u8], value: &[u8])[−]

Append a Leaf node

fn begin_branch(
    &mut self,
    maybe_partial: Option<&[u8]>,
    maybe_value: Option<&[u8]>,
    has_children: impl Iterator<Item = bool>
)[−]

Start a new Branch node, possibly with a value; takes a list indicating which slots in the Branch node has further child nodes.

Append an Extension node

fn append_substream<H: Hasher>(&mut self, other: Self)[−]

Append a Branch of Extension substream

fn out(self) -> Vec<u8>[−]

Return the finished TrieStream as a vector of bytes.

fn append_empty_child(&mut self)[−]

Append an empty child node. Optional.

fn end_branch(&mut self, _value: Option<&[u8]>)[−]

Wrap up a Branch node portion of a TrieStream and append the value stored on the Branch (if any).
