Struct AssertionValidityEvent 

pub struct AssertionValidityEvent {
    pub validity_event_uuid: Uuid,
    pub assertion_uuid: Uuid,
    pub valid_from_micros: Option<i64>,
    pub valid_to_micros: Option<i64>,
    pub reasoning_uuid: Option<Uuid>,
    pub provenance_uuid: Uuid,
    pub recorded_at_micros: i64,
    pub contract_version: u32,
}

One immutable correction to an assertion’s valid-time interpretation.

Fields

validity_event_uuid: Uuid

Caller-supplied UUIDv7 identity/idempotency key.

assertion_uuid: Uuid

Existing immutable assertion.

valid_from_micros: Option<i64>

Inclusive lower bound, or unbounded when absent.

valid_to_micros: Option<i64>

Exclusive upper bound, or unbounded when absent.

reasoning_uuid: Option<Uuid>

Optional existing immutable reasoning record.

provenance_uuid: Uuid

Existing producing provenance event.

recorded_at_micros: i64

Mandatory transaction time.

contract_version: u32

Frozen record contract.

Implementations

impl AssertionValidityEvent

pub fn new( validity_event_uuid: Uuid, assertion_uuid: Uuid, valid_from_micros: Option<i64>, valid_to_micros: Option<i64>, reasoning_uuid: Option<Uuid>, provenance_uuid: Uuid, recorded_at_micros: i64, ) -> Result<Self, KnowledgeError>

Validate and construct one immutable half-open interval event.

pub fn contains(&self, valid_time_micros: i64) -> bool

Evaluate the half-open interval [valid_from, valid_to).

Equal bounds form a valid empty interval. Missing bounds are unbounded.
