Struct DataEntity 

pub struct DataEntity {
    pub id: String,
    pub type_: DataType,
    pub dynamic_entity: Option<HashMap<String, EntityValue>>,
}

Represents a data entity with an identifier, type, and dynamic properties.

DataEntity is designed to encapsulate an entity with a unique identifier (id), a specific type (type_), and a set of dynamic properties (dynamic_entity). This struct is used to handle Data entities that have a predefined structure along with additional properties that may vary.

Fields

id: String

URI to data

type_: DataType

Defined type, if file MUST be type ‘File’

dynamic_entity: Option<HashMap<String, EntityValue>>

Additional metadata

Implementations

impl DataEntity

pub fn get_property_value( &self, property: &str, ) -> Option<(String, EntityValue)>

Gets ID and value of specific target property

pub fn find_value_details( &self, target_value: &EntityValue, ) -> Option<(String, String)>

Searches through every value in the struct to find the key for a matching input value.

Arguments

• target_value - The value to search for, as an EntityValue.

Returns

An Option<String> containing the key if the value exists, or None otherwise.

pub fn get_linked_ids(&self) -> Vec<Id>

Trait Implementations

impl Clone for DataEntity

fn clone(&self) -> DataEntity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomSerialize for DataEntity

Provides custom serialization for DataEntity.

Implements custom serialization logic as defined in the CustomSerialize trait. This allows DataEntity to be serialized with custom rules, especially for the dynamic properties in the dynamic_entity field.

fn dynamic_entity(&self) -> Option<&HashMap<String, EntityValue>>

fn id(&self) -> &String

fn type_(&self) -> &DataType

fn custom_serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

impl Debug for DataEntity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataEntity

Custom deserialization implementation for DataEntity.

This method provides a tailored approach to convert serialized data (like JSON) into a DataEntity instance. It employs a DataEntityVisitor for map-based deserialization.

The method expects the serialized data to be in a map format (key-value pairs), which is typical for formats like JSON. It specifically looks for @id and @type keys to fill the corresponding fields of DataEntity. All other keys are treated as dynamic properties and are stored in a HashMap.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataEntity

Custom display formatting for DataEntity

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

Formats the value using the given formatter.

impl DynamicEntityManipulation for DataEntity

Provides functionality for manipulating dynamic properties of a DataEntity.

This trait implementation allows for adding, modifying, and removing dynamic properties stored in the dynamic_entity field of DataEntity.

fn dynamic_entity(&mut self) -> &mut Option<HashMap<String, EntityValue>>

Gets a mutable reference to the dynamic entity’s underlying HashMap.

fn dynamic_entity_immut(&self) -> &Option<HashMap<String, EntityValue>>

Gets an immutable reference to the dynamic entity’s underlying HashMap.

fn add_dynamic_fields(&mut self, values: HashMap<String, EntityValue>)

Adds dynamic fields to the entity

fn add_string_value(&mut self, key: String, value: String)

Adds a string value to the dynamic entity.

fn add_id_value(&mut self, key: String, value: Id)

Adds an identifier value to the dynamic entity.

fn remove_field(&mut self, key: &str)

Removes a field from the dynamic entity.

fn search_value(&self, search_value: &EntityValue) -> bool

Searches for a specific value within the dynamic entity.

fn search_properties_for_value( &self, search_property: &str, ) -> Option<EntityValue>

Finds keys within the RO-Crate matching a specified key or retrieves all keys.

fn get_all_keys(&self) -> Vec<String>

Get all keys containing within a dynamic_entity

fn remove_matching_value(&mut self, target_id: &str)

Method to remove a matching value from the dynamic_entity field.

fn update_matching_id(&mut self, id_old: &str, id_new: &str) -> Option<bool>

Updates all occurrences of a specific ID with a new ID within the dynamic entity fields.

impl Serialize for DataEntity

Custom serde serialization implementation for DataEntity.

Delegates the serialization process to the custom_serialize method provided by the CustomSerialize trait implementation.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
