Struct EntityRecord 

pub struct EntityRecord {
    pub fact: String,
    pub last_seen: DateTime<Utc>,
    pub created_at: DateTime<Utc>,
}

One entity’s recorded fact plus provenance metadata.

last_seen is refreshed every time EntityMemory::set_entity or EntityMemory::touch runs; reads do not advance it. created_at is set once on first insertion and preserved across subsequent updates so the audit trail of “when did we first learn this entity?” stays intact.

Fields

fact: String

The current fact recorded for this entity.

last_seen: DateTime<Utc>

Wall-clock time the fact was last confirmed (set or touched).

created_at: DateTime<Utc>

Wall-clock time the entity was first observed.

Trait Implementations

impl Clone for EntityRecord

fn clone(&self) -> EntityRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EntityRecord

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EntityRecord

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

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 EntityRecord

impl StructuralPartialEq for EntityRecord
