Struct differential_dataflow::logging::TraceShare

pub struct TraceShare {
    pub operator: usize,
    pub diff: isize,
}

Either the start or end of a merge event.

Fields

operator: usize

Operator identifier.

diff: isize

Change in number of shares.

Trait Implementations

impl Abomonation for TraceShare

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 TraceShare

fn clone(&self) -> TraceShare

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraceShare

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

Formats the value using the given formatter.

impl From<TraceShare> for DifferentialEvent

fn from(e: TraceShare) -> Self

Converts to this type from the input type.

impl Ord for TraceShare

fn cmp(&self, other: &TraceShare) -> 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 PartialEq for TraceShare

fn eq(&self, other: &TraceShare) -> 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 for TraceShare

fn partial_cmp(&self, other: &TraceShare) -> 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.
