Struct HistoryEntry 

pub struct HistoryEntry {
    pub claim_ref: ClaimRef,
    pub value: Value,
    pub valid_from: Option<DateTime<Utc>>,
    pub valid_until: Option<DateTime<Utc>>,
    pub status: HistoryEntryStatus,
    pub provenance: String,
    pub value_confidence: f32,
}

Re-export core’s HistoryEntry so callers only need use mempill::HistoryEntry. One slot in the history timeline for a subject-line.

status is derived from is_live in the canonical fold — the Current entry is exactly the claim that recall / query_memory would return as primary.

Fields

claim_ref: ClaimRef

Stable reference to the underlying claim (UUID).

value: Value

The asserted value for this claim.

valid_from: Option<DateTime<Utc>>

Start of the valid-time window, or None if unknown.

valid_until: Option<DateTime<Utc>>

Effective end of the slot: equals the successor’s canonical ordering key, or None for the open-ended current slot.

status: HistoryEntryStatus

Whether this claim is the live belief or has been superseded.

provenance: String

Human-readable provenance label (e.g. "External/UserAsserted").

value_confidence: f32

Confidence in the claim’s value (0.0–1.0).

Trait Implementations

impl Clone for HistoryEntry

fn clone(&self) -> HistoryEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HistoryEntry

fn deserialize<__D>( __deserializer: __D, ) -> Result<HistoryEntry, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HistoryEntry

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
