Struct BitemporalPoint 

pub struct BitemporalPoint {
    pub valid_at: i64,
    pub as_of: i64,
}

A bitemporal point representing both valid and transaction time.

This is useful for querying “what was known to be true at time T1, as of system time T2?”

Fields

valid_at: i64

Point in valid time to query.

as_of: i64

Point in transaction time to query.

Implementations

impl BitemporalPoint

pub const fn new(valid_at: i64, as_of: i64) -> Self

Creates a bitemporal point.

pub fn now() -> Self

Creates a bitemporal point for “now” in both dimensions.

pub const fn is_visible( &self, valid_time: &ValidTimeRange, tx_time: &TransactionTime, ) -> bool

Checks if a record with given temporal metadata is visible at this point.

Trait Implementations

impl Clone for BitemporalPoint

fn clone(&self) -> BitemporalPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitemporalPoint

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

Formats the value using the given formatter.

impl Default for BitemporalPoint

fn default() -> Self

Returns the “default value” for a type.

impl Display for BitemporalPoint

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

Formats the value using the given formatter.

impl Hash for BitemporalPoint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BitemporalPoint

fn eq(&self, other: &BitemporalPoint) -> 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.
