Struct cfx_storage::OwnedNodeSet

pub struct OwnedNodeSet { /* private fields */ }

A container to store information about owned nodes.

Implementations

impl OwnedNodeSet

pub fn insert( &mut self, val: NodeRefDeltaMpt, original_db_key: Option<u32> ) -> bool

Insertion takes an extra argument original_db_key to indicate where a dirty node comes from. If it’s a new node, pass None. If it’s a committed node, the argument is ignored.

pub fn remove(&mut self, val: &NodeRefDeltaMpt) -> bool

pub fn contains(&self, val: &NodeRefDeltaMpt) -> bool

pub fn iter(&self) -> Iter<'_>

pub fn get_original_db_key(&self, index: u32) -> Option<u32>

Trait Implementations

impl Debug for OwnedNodeSet

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

Formats the value using the given formatter.

impl Default for OwnedNodeSet

fn default() -> OwnedNodeSet

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a OwnedNodeSet

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

type Item = NodeRefDeltaMpt

The type of the elements being iterated over.

fn into_iter(self) -> Iter<'a>

Creates an iterator from a value.
