Enum casper_execution_engine::storage::trie::Pointer

pub enum Pointer {
    LeafPointer(Digest),
    NodePointer(Digest),
}

Represents a pointer to the next object in a Merkle Trie

Variants

LeafPointer(Digest)

Leaf pointer.

NodePointer(Digest)

Node pointer.

Implementations

impl Pointer

pub fn hash(&self) -> &Digest

Borrows the inner hash from a Pointer.

pub fn into_hash(self) -> Digest

Takes ownership of the hash, consuming this Pointer.

pub fn update(&self, hash: Digest) -> Self

Creates a new owned Pointer with a new Digest.

Trait Implementations

impl Clone for Pointer

fn clone(&self) -> Pointer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pointer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Pointer

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

Deserialize this value from the given Serde deserializer.

impl FromBytes for Pointer

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq for Pointer

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Pointer

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

Serialize this value into the given Serde serializer.

impl ToBytes for Pointer

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn into_bytes(self) -> Result<Vec<u8>, Error>where Self: Sized,

Consumes self and serializes to a Vec<u8>.
