Struct differential_dataflow::dynamic::pointstamp::PointStampSummary

pub struct PointStampSummary<TS> {
    pub retain: Option<usize>,
    pub actions: Vec<TS>,
}

Describes an action on a PointStamp: truncation to length followed by actions.

Fields

retain: Option<usize>

Number of leading coordinates to retain.

A None value indicates that all coordinates should be retained.

actions: Vec<TS>

Summary actions to apply to all coordinates.

If actions.len() is greater than retain, a timestamp should be extended by T::minimum() in order to be subjected to actions.

Trait Implementations

impl<TS: Clone> Clone for PointStampSummary<TS>

fn clone(&self) -> PointStampSummary<TS>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<TS: Debug> Debug for PointStampSummary<TS>

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

Formats the value using the given formatter.

impl<TS: Default> Default for PointStampSummary<TS>

fn default() -> PointStampSummary<TS>

Returns the “default value” for a type.

impl<'de, TS> Deserialize<'de> for PointStampSummary<TS>

where TS: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<TS: Hash> Hash for PointStampSummary<TS>

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<TS: Ord> Ord for PointStampSummary<TS>

fn cmp(&self, other: &PointStampSummary<TS>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<TS: PartialEq> PartialEq for PointStampSummary<TS>

fn eq(&self, other: &PointStampSummary<TS>) -> 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<TS: PartialOrd> PartialOrd for PointStampSummary<TS>

fn partial_cmp(&self, other: &PointStampSummary<TS>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<TS: PartialOrder> PartialOrder for PointStampSummary<TS>

fn less_equal(&self, other: &Self) -> bool

Returns true iff one element is less than or equal to the other.

fn less_than(&self, other: &Rhs) -> bool

Returns true iff one element is strictly less than the other.

impl<T: Timestamp> PathSummary<PointStamp<T>> for PointStampSummary<T::Summary>

fn results_in(&self, timestamp: &PointStamp<T>) -> Option<PointStamp<T>>

Advances a timestamp according to the timestamp actions on the path.

fn followed_by(&self, other: &Self) -> Option<Self>

Composes this path summary with another path summary.

impl<TS> Serialize for PointStampSummary<TS>

where TS: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
