Struct Entity 

pub struct Entity {
    pub id: EntityId,
    pub name: String,
    pub entity_type: String,
    pub attrs: Value,
    pub valid_from: Option<DateTime<Utc>>,
    pub valid_to: Option<DateTime<Utc>>,
    pub source_doc_id: Option<String>,
    pub confidence: f32,
    pub created_at: DateTime<Utc>,
}

A node in the knowledge graph.

Fields

id: EntityId

Stable id (UUID v4 by default).

name: String

Human-readable name ("Damien", "Aonyx Agent", "GPT-5").

entity_type: String

Free-form type tag ("person", "project", "model").

attrs: Value

Arbitrary structured attributes serialised as JSON.

valid_from: Option<DateTime<Utc>>

Lower bound of validity (inclusive). None = “since forever”.

valid_to: Option<DateTime<Utc>>

Upper bound of validity (exclusive). None = “still true”.

source_doc_id: Option<String>

Optional pointer to the document this entity was extracted from.

confidence: f32

Confidence in the assertion (0.0–1.0).

created_at: DateTime<Utc>

Wall-clock creation time.

Implementations

impl Entity

pub fn new(name: impl Into<String>, entity_type: impl Into<String>) -> Self

Build a new entity with sensible defaults (confidence = 1.0, no validity bounds).

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Entity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Entity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Entity

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
