Struct differential_dataflow::logging::MergeEvent

pub struct MergeEvent {
    pub operator: usize,
    pub scale: usize,
    pub length1: usize,
    pub length2: usize,
    pub complete: Option<usize>,
}

Either the start or end of a merge event.

Fields

operator: usize

Operator identifier.

scale: usize

Which order of magnitude.

length1: usize

Length of first trace.

length2: usize

Length of second trace.

complete: Option<usize>

None implies a start.

Trait Implementations

impl Abomonation for MergeEvent

unsafe fn entomb<W: Write>(&self, _write: &mut W) -> Result<()>

Write any additional information about &self beyond its binary representation.

fn extent(&self) -> usize

Reports the number of further bytes required to entomb self.

unsafe fn exhume<'a, 'b>(
    &'a mut self,
    bytes: &'b mut [u8]
) -> Option<&'b mut [u8]>

Recover any information for &mut self not evident from its binary representation.

impl Clone for MergeEvent

fn clone(&self) -> MergeEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MergeEvent

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

Formats the value using the given formatter.

impl From<MergeEvent> for DifferentialEvent

fn from(e: MergeEvent) -> Self

Converts to this type from the input type.

impl Ord for MergeEvent

fn cmp(&self, other: &MergeEvent) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MergeEvent> for MergeEvent

fn eq(&self, other: &MergeEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<MergeEvent> for MergeEvent

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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