Struct InMemoryTrieDB 

pub struct InMemoryTrieDB { /* private fields */ }

InMemory implementation for the TrieDB trait, with get and put operations.

Implementations

impl InMemoryTrieDB

pub const fn new(map: NodeMap) -> Self

pub const fn new_with_prefix(map: NodeMap, prefix: Nibbles) -> Self

pub fn new_empty() -> Self

pub fn from_nodes( root_hash: H256, state_nodes: &BTreeMap<H256, Node>, ) -> Result<Self, TrieError>

pub fn inner(&self) -> NodeMap

Trait Implementations

impl Default for InMemoryTrieDB

fn default() -> InMemoryTrieDB

Returns the “default value” for a type.

impl TrieDB for InMemoryTrieDB

fn get(&self, key: Nibbles) -> Result<Option<Vec<u8>>, TrieError>

fn put_batch( &self, key_values: Vec<(Nibbles, Vec<u8>)>, ) -> Result<(), TrieError>

fn put_batch_no_alloc( &self, key_values: &[(Nibbles, Node)], ) -> Result<(), TrieError>

fn put(&self, key: Nibbles, value: Vec<u8>) -> Result<(), TrieError>

fn commit(&self) -> Result<(), TrieError>

Commits any pending changes to the underlying storage For read-only or in-memory implementations, this is a no-op
