Struct casper_execution_engine::storage::trie::PointerBlock

pub struct PointerBlock(_);

Represents the underlying structure of a node in a Merkle Trie

Implementations

impl PointerBlock

pub fn new() -> Self

No-arg constructor for PointerBlock. Delegates to Default::default().

pub fn from_indexed_pointers(indexed_pointers: &[(u8, Pointer)]) -> Self

Constructs a PointerBlock from a slice of indexed Pointers.

pub fn as_indexed_pointers(&self) -> impl Iterator<Item = (u8, Pointer)> + '_

Deconstructs a PointerBlock into an iterator of indexed Pointers.

pub fn child_count(&self) -> usize

Gets the count of children for this PointerBlock.

Trait Implementations

impl Clone for PointerBlock

fn clone(&self) -> PointerBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointerBlock

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

Formats the value using the given formatter.

impl Default for PointerBlock

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PointerBlock

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

Deserialize this value from the given Serde deserializer.

impl From<[Option<Pointer>; 256]> for PointerBlock

fn from(src: PointerBlockArray) -> Self

Converts to this type from the input type.

impl FromBytes for PointerBlock

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

Deserializes the slice into Self.

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

Deserializes the Vec<u8> into Self.

impl Index<Range<usize>> for PointerBlock

type Output = [Option<Pointer>]

The returned type after indexing.

fn index(&self, index: Range<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for PointerBlock

type Output = [Option<Pointer>]

The returned type after indexing.

fn index(&self, index: RangeFrom<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for PointerBlock

type Output = [Option<Pointer>]

The returned type after indexing.

fn index(&self, index: RangeFull) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for PointerBlock

type Output = [Option<Pointer>]

The returned type after indexing.

fn index(&self, index: RangeTo<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<usize> for PointerBlock

type Output = Option<Pointer>

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for PointerBlock

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq<PointerBlock> for PointerBlock

fn eq(&self, other: &PointerBlock) -> 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 PointerBlock

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 PointerBlock

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

Consumes self and serializes to a Vec<u8>.

impl Copy for PointerBlock
