Trait Implementations

impl Default for Hash256RlpTrieStream

fn default() -> Hash256RlpTrieStream

Returns the “default value” for a type.

impl TrieStream for Hash256RlpTrieStream

fn new() -> Self

Construct a new TrieStream

fn append_empty_data(&mut self)

Append an Empty node

fn begin_branch( &mut self, _maybe_key: Option<&[u8]>, _maybe_value: Option<TrieStreamValue<'_>>, _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.

fn append_empty_child(&mut self)

Append an empty child node. Optional.

fn end_branch(&mut self, value: Option<TrieStreamValue<'_>>)

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

fn append_leaf(&mut self, key: &[u8], value: TrieStreamValue<'_>)

Append a Leaf node

fn append_extension(&mut self, key: &[u8])

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.
