Struct LineageNode 

pub struct LineageNode {
    pub id: String,
    pub node_type: NodeType,
    pub entity_id: String,
    pub metadata: HashMap<String, String>,
    pub created_at: DateTime<Utc>,
}

Lineage node representing a data entity.

Fields

id: String

Node ID.

node_type: NodeType

Node type.

entity_id: String

Entity URI or identifier.

metadata: HashMap<String, String>

Node metadata.

created_at: DateTime<Utc>

Created timestamp.

Implementations

impl LineageNode

pub fn new(node_type: NodeType, entity_id: String) -> Self

Create a new lineage node.

pub fn with_metadata(self, key: String, value: String) -> Self

Add metadata.

Trait Implementations

impl Clone for LineageNode

fn clone(&self) -> LineageNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineageNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LineageNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LineageNode

fn eq(&self, other: &LineageNode) -> 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 Serialize for LineageNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for LineageNode
