Struct reference_trie::ReferenceTrieStreamNoExt

pub struct ReferenceTrieStreamNoExt { /* private fields */ }

Reference implementation of a TrieStream without extension.

Trait Implementations

impl Clone for ReferenceTrieStreamNoExt

fn clone(&self) -> ReferenceTrieStreamNoExt

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for ReferenceTrieStreamNoExt

fn default() -> ReferenceTrieStreamNoExt

Returns the “default value” for a type.

impl TrieStream for ReferenceTrieStreamNoExt

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: TrieStreamValue<'_>)

Append a Leaf node

fn begin_branch(
    &mut self,
    maybe_partial: 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_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.

fn append_empty_child(&mut self)

Append an empty child node. Optional.

fn end_branch(&mut self, _value: Option<Value<'_>>)

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