Struct StorageTrieUpdates

pub struct StorageTrieUpdates {
    pub is_deleted: bool,
    pub storage_nodes: HashMap<Nibbles, BranchNodeCompact, RandomState>,
    pub removed_nodes: HashSet<Nibbles, RandomState>,
}

Available on crate feature trie only.

Trie updates for storage trie of a single account.

Fields

is_deleted: bool

Flag indicating whether the trie was deleted.

storage_nodes: HashMap<Nibbles, BranchNodeCompact, RandomState>

Collection of updated storage trie nodes.

removed_nodes: HashSet<Nibbles, RandomState>

Collection of removed storage trie nodes.

Implementations

impl StorageTrieUpdates

pub fn new( updates: impl IntoIterator<Item = (Nibbles, BranchNodeCompact)>, ) -> StorageTrieUpdates

Available on crate feature test-utils only.

Creates a new storage trie updates that are not marked as deleted.

impl StorageTrieUpdates

pub fn deleted() -> StorageTrieUpdates

Returns empty storage trie updates with deleted set to true.

pub fn len(&self) -> usize

Returns the length of updated nodes.

pub const fn is_deleted(&self) -> bool

Returns true if the trie was deleted.

pub const fn storage_nodes_ref( &self, ) -> &HashMap<Nibbles, BranchNodeCompact, RandomState>

Returns reference to updated storage nodes.

pub const fn removed_nodes_ref(&self) -> &HashSet<Nibbles, RandomState>

Returns reference to removed storage nodes.

pub fn is_empty(&self) -> bool

Returns true if storage updates are empty.

pub fn set_deleted(&mut self, deleted: bool)

Sets deleted flag on the storage trie.

pub fn extend(&mut self, other: StorageTrieUpdates)

Extends storage trie updates.

pub fn extend_ref(&mut self, other: &StorageTrieUpdates)

Extends storage trie updates.

Slightly less efficient than Self::extend, but preferred to extend(other.clone()).

pub fn finalize( &mut self, hash_builder: HashBuilder, removed_keys: HashSet<Nibbles, RandomState>, )

Finalize storage trie updates for by taking updates from walker and hash builder.

pub fn into_sorted(self) -> StorageTrieUpdatesSorted

Convert storage trie updates into StorageTrieUpdatesSorted.

Trait Implementations

impl Clone for StorageTrieUpdates

fn clone(&self) -> StorageTrieUpdates

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageTrieUpdates

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

Formats the value using the given formatter.

impl Default for StorageTrieUpdates

fn default() -> StorageTrieUpdates

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageTrieUpdates

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'de> DeserializeAs<'de, StorageTrieUpdates> for StorageTrieUpdates<'de>

fn deserialize_as<D>( deserializer: D, ) -> Result<StorageTrieUpdates, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a StorageTrieUpdates> for StorageTrieUpdates<'a>

fn from(value: &'a StorageTrieUpdates) -> StorageTrieUpdates<'a>

Converts to this type from the input type.

impl<'a> From<StorageTrieUpdates<'a>> for StorageTrieUpdates

fn from(value: StorageTrieUpdates<'a>) -> StorageTrieUpdates

Converts to this type from the input type.

impl PartialEq for StorageTrieUpdates

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for StorageTrieUpdates

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.

impl SerializeAs<StorageTrieUpdates> for StorageTrieUpdates<'_>

fn serialize_as<S>( source: &StorageTrieUpdates, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for StorageTrieUpdates

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.
