Enum NodeStateUpdates

pub enum NodeStateUpdates {
    Delta {
        by_partition: IndexMap<PartitionNumber, PartitionStateUpdates>,
    },
}

A description of all updates that happened to a state of a single Node. Note: currently, we do not support any Node-wide changes (e.g. deleting entire Node); however, we use an enum for potential future development.

Variants

Delta

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

Fields

by_partition: IndexMap<PartitionNumber, PartitionStateUpdates>

Implementations

impl NodeStateUpdates

pub fn empty() -> NodeStateUpdates

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

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

pub fn of_partition( &mut self, partition_num: PartitionNumber, ) -> &mut PartitionStateUpdates

Starts a Partition-level update.

pub fn of_partition_ref( &self, partition_num: PartitionNumber, ) -> Option<&PartitionStateUpdates>

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

Trait Implementations

impl<X> Categorize<X> for NodeStateUpdates

where X: CustomValueKind,

fn value_kind() -> ValueKind<X>

impl Clone for NodeStateUpdates

fn clone(&self) -> NodeStateUpdates

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CreateDatabaseUpdates for NodeStateUpdates

type DatabaseUpdates = NodeDatabaseUpdates

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

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 NodeStateUpdates

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

Formats the value using the given formatter.

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

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

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

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

impl Default for NodeStateUpdates

fn default() -> NodeStateUpdates

Returns the “default value” for a type.

impl<C> Describe<C> for NodeStateUpdates

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 NodeStateUpdates

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 NodeStateUpdates

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

where X: CustomValueKind,

fn get_discriminator(&self) -> u8

fn get_length(&self) -> usize

impl Eq for NodeStateUpdates

impl StructuralPartialEq for NodeStateUpdates
