Enum PartitionStateUpdates 

pub enum PartitionStateUpdates {
    Delta {
        by_substate: IndexMap<SubstateKey, DatabaseUpdate>,
    },
    Batch(BatchPartitionStateUpdate),
}

A description of all updates that happened to a state of a single Partition.

Variants

Delta

A “delta” update to a Partition, touching only selected Substates. Contains indexed Substate-level updates, captured in the order of first update operation to a Substate.

Fields

by_substate: IndexMap<SubstateKey, DatabaseUpdate>

Batch(BatchPartitionStateUpdate)

A batch update.

Implementations

impl PartitionStateUpdates

pub fn set_substate<'a>( self, key: impl ResolvableSubstateKey<'a>, value: impl ScryptoEncode, ) -> PartitionStateUpdates

pub fn mut_set_substate<'a>( &mut self, key: impl ResolvableSubstateKey<'a>, value: impl ScryptoEncode, )

pub fn delete(&mut self)

Resets the partition to an empty state.

pub fn contains_set_update_for(&self, key: &SubstateKey) -> bool

pub fn mut_update_substate<'a>( &mut self, key: impl ResolvableSubstateKey<'a>, database_update: DatabaseUpdate, )

pub fn update_substate<'a>( self, key: impl ResolvableSubstateKey<'a>, database_update: DatabaseUpdate, ) -> PartitionStateUpdates

pub fn mut_update_substates( &mut self, updates: impl IntoIterator<Item = (SubstateKey, DatabaseUpdate)>, )

Applies the given updates on top of the current updates to the partition.

pub fn update_substates( self, updates: impl IntoIterator<Item = (SubstateKey, DatabaseUpdate)>, ) -> PartitionStateUpdates

pub fn rebuild_without_empty_entries(self) -> Option<PartitionStateUpdates>

pub fn iter_map_entries( &self, ) -> Box<dyn Iterator<Item = (&Vec<u8>, DatabaseUpdateRef<'_>)> + '_>

Trait Implementations

impl<X> Categorize<X> for PartitionStateUpdates

where X: CustomValueKind,

fn value_kind() -> ValueKind<X>

impl Clone for PartitionStateUpdates

fn clone(&self) -> PartitionStateUpdates

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CreateDatabaseUpdates for PartitionStateUpdates

type DatabaseUpdates = PartitionDatabaseUpdates

fn create_database_updates_with_mapper<M>(&self) -> PartitionDatabaseUpdates

where M: DatabaseKeyMapper,

Uses the given DatabaseKeyMapper to express self using database-level key encoding.

fn create_database_updates(&self) -> Self::DatabaseUpdates

Uses the default DatabaseKeyMapper, SpreadPrefixKeyMapper, to express self using database-level key encoding.

impl Debug for PartitionStateUpdates

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

Formats the value using the given formatter.

impl<D, X> Decode<X, D> for PartitionStateUpdates

where D: Decoder<X>, X: CustomValueKind,

fn decode_body_with_value_kind( decoder: &mut D, value_kind: ValueKind<X>, ) -> Result<PartitionStateUpdates, DecodeError>

Decodes the type from the decoder, which should match a preloaded value kind.

impl Default for PartitionStateUpdates

fn default() -> PartitionStateUpdates

Returns the “default value” for a type.

impl<C> Describe<C> for PartitionStateUpdates

where C: CustomTypeKind<RustTypeId>,

const TYPE_ID: RustTypeId

The TYPE_ID should give a unique identifier for its SBOR schema type. An SBOR schema type capture details about the SBOR payload, how it should be interpreted, validated and displayed.

fn type_data() -> TypeData<C, RustTypeId>

Returns the local schema for the given type.

fn add_all_dependencies(aggregator: &mut TypeAggregator<C>)

For each type referenced in get_local_type_data, we need to ensure that the type and all of its own references get added to the aggregator.

impl<E, X> Encode<X, E> for PartitionStateUpdates

where E: Encoder<X>, X: CustomValueKind,

fn encode_value_kind(&self, encoder: &mut E) -> Result<(), EncodeError>

Encodes the SBOR value’s kind to the encoder

fn encode_body(&self, encoder: &mut E) -> Result<(), EncodeError>

Encodes the SBOR body of the type to the encoder.

impl PartialEq for PartitionStateUpdates

fn eq(&self, other: &PartitionStateUpdates) -> 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<X> SborEnum<X> for PartitionStateUpdates

where X: CustomValueKind,

fn get_discriminator(&self) -> u8

fn get_length(&self) -> usize

impl Eq for PartitionStateUpdates
