Struct DatabaseUpdates

pub struct DatabaseUpdates {
    pub node_updates: IndexMap<Vec<u8>, NodeDatabaseUpdates>,
}

A canonical description of all database updates to be applied. Note: this struct can be migrated to an enum if we ever have a need for database-wide batch changes (see PartitionDatabaseUpdates enum).

Fields

node_updates: IndexMap<Vec<u8>, NodeDatabaseUpdates>

Node-level updates.

Implementations

impl DatabaseUpdates

pub fn node_ids(&self) -> impl Iterator<Item = NodeId>

impl DatabaseUpdates

pub fn from_delta_maps( maps: IndexMap<DbPartitionKey, IndexMap<DbSortKey, DatabaseUpdate>>, ) -> DatabaseUpdates

Constructs an instance from the given legacy representation (a map of maps), which is only capable of specifying “deltas” (i.e. individual substate changes; no partition deletes).

Note: This method is only meant for tests/demos - with regular Engine usage, the DatabaseUpdates can be obtained directly from the receipt.

Trait Implementations

impl<X> Categorize<X> for DatabaseUpdates

where X: CustomValueKind,

fn value_kind() -> ValueKind<X>

impl Clone for DatabaseUpdates

fn clone(&self) -> DatabaseUpdates

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseUpdates

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

Formats the value using the given formatter.

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

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

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

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

impl Default for DatabaseUpdates

fn default() -> DatabaseUpdates

Returns the “default value” for a type.

impl<C> Describe<C> for DatabaseUpdates

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 DatabaseUpdates

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 From<StagingDatabaseUpdates> for DatabaseUpdates

fn from(value: StagingDatabaseUpdates) -> DatabaseUpdates

Converts to this type from the input type.

impl PartialEq for DatabaseUpdates

fn eq(&self, other: &DatabaseUpdates) -> 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> SborTuple<X> for DatabaseUpdates

where X: CustomValueKind,

fn get_length(&self) -> usize

impl Eq for DatabaseUpdates

impl StructuralPartialEq for DatabaseUpdates
