Struct BranchNode 

pub struct BranchNode {
    pub stack: Vec<RlpNode>,
    pub state_mask: TrieMask,
}

Re-export A branch node in an Ethereum Merkle Patricia Trie.

Branch node is a 17-element array consisting of 16 slots that correspond to each hexadecimal character and an additional slot for a value. We do exclude the node value since all paths have a fixed size.

Fields

stack: Vec<RlpNode>

The collection of RLP encoded children.

state_mask: TrieMask

The bitmask indicating the presence of children at the respective nibble positions

Implementations

impl BranchNode

pub const fn new(stack: Vec<RlpNode>, state_mask: TrieMask) -> BranchNode

Creates a new branch node with the given stack and state mask.

pub fn as_ref(&self) -> BranchNodeRef<'_>

Return branch node as BranchNodeRef.

Trait Implementations

impl Clone for BranchNode

fn clone(&self) -> BranchNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BranchNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decodable for BranchNode

fn decode(buf: &mut &[u8]) -> Result<BranchNode, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl Default for BranchNode

fn default() -> BranchNode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BranchNode

fn deserialize<__D>( __deserializer: __D, ) -> Result<BranchNode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for BranchNode

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl Eq for BranchNode

impl PartialEq for BranchNode

fn eq(&self, other: &BranchNode) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for BranchNode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
