Enum TemporalScope 

pub enum TemporalScope {
    PointInTime(DateTime<Utc>),
    Range {
        start: DateTime<Utc>,
        end: DateTime<Utc>,
    },
    AnyTime,
    Current,
}

A temporal scope for queries.

Variants

PointInTime(DateTime<Utc>)

Query at a specific point in time

Range

Query across a time range

Fields

start: DateTime<Utc>

Start of the time range (inclusive)

end: DateTime<Utc>

End of the time range (exclusive)

AnyTime

Query for entities valid at any point

Current

Query for currently valid entities (no end date)

Implementations

impl TemporalScope

pub fn contains(&self, entity: &Entity) -> bool

Check if an entity is valid within this scope.

Trait Implementations

impl Clone for TemporalScope

fn clone(&self) -> TemporalScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemporalScope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TemporalScope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TemporalScope

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
