impl FlashSubstateDatabase

pub fn standard() -> Self

pub fn database_updates(self) -> DatabaseUpdates

Trait Implementations

impl Clone for FlashSubstateDatabase

fn clone(&self) -> FlashSubstateDatabase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommittableSubstateDatabase for FlashSubstateDatabase

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

Commits state changes to the database.

impl Debug for FlashSubstateDatabase

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

Formats the value using the given formatter.

impl PartialEq for FlashSubstateDatabase

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

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

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 = PartitionEntry> + '_>

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.
