Implementations

impl InMemorySubstateDatabase

pub fn standard() -> InMemorySubstateDatabase

Trait Implementations

impl Clone for InMemorySubstateDatabase

fn clone(&self) -> InMemorySubstateDatabase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommittableSubstateDatabase for InMemorySubstateDatabase

fn commit(&mut self, database_updates: &DatabaseUpdates)

Commits state changes to the database.

impl Debug for InMemorySubstateDatabase

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

Formats the value using the given formatter.

impl ListableSubstateDatabase for InMemorySubstateDatabase

fn list_partition_keys(&self) -> Box<dyn Iterator<Item = DbPartitionKey> + '_>

Iterates over all partition keys, in an arbitrary order.

impl PartialEq for InMemorySubstateDatabase

fn eq(&self, other: &InMemorySubstateDatabase) -> 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 SubstateDatabase for InMemorySubstateDatabase

fn get_substate( &self, partition_key: &DbPartitionKey, sort_key: &DbSortKey ) -> Option<Vec<u8>>

Reads a substate value by its partition and sort key, or Option::None if missing.

fn list_entries_from( &self, partition_key: &DbPartitionKey, from_sort_key: Option<&DbSortKey> ) -> Box<dyn Iterator<Item = (DbSortKey, Vec<u8>)> + '_>

Iterates over all entries of the given partition (starting either from the beginning, or from the given DbSortKey), in a lexicographical order (ascending) of the DbSortKeys. Note: If the exact given starting key does not exist, the iteration starts with its immediate successor.

fn list_entries( &self, partition_key: &DbPartitionKey ) -> Box<dyn Iterator<Item = (DbSortKey, Vec<u8>)> + '_>

Iterates over all entries of the given partition, in a lexicographical order (ascending) of the DbSortKeys. This is a convenience method, equivalent to Self::list_entries_from() with the starting key set to None.
