impl DifferentialEvent

pub const fn is_batch(&self) -> bool

Returns true if the differential_event is [Batch].

pub const fn is_merge(&self) -> bool

Returns true if the differential_event is [Merge].

pub const fn is_drop(&self) -> bool

Returns true if the differential_event is Drop.

pub const fn is_trace_share(&self) -> bool

Returns true if the differential_event is TraceShare.

Trait Implementations

impl Archive for DifferentialEvent

where BatchEvent: Archive, MergeEvent: Archive, DropEvent: Archive, MergeShortfall: Archive, TraceShare: Archive,

type Archived = ArchivedDifferentialEvent

The archived representation of this type.

type Resolver = DifferentialEventResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for DifferentialEvent

fn clone(&self) -> DifferentialEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DifferentialEvent

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<DifferentialEvent, __D> for Archived<DifferentialEvent>

where BatchEvent: Archive, Archived<BatchEvent>: Deserialize<BatchEvent, __D>, MergeEvent: Archive, Archived<MergeEvent>: Deserialize<MergeEvent, __D>, DropEvent: Archive, Archived<DropEvent>: Deserialize<DropEvent, __D>, MergeShortfall: Archive, Archived<MergeShortfall>: Deserialize<MergeShortfall, __D>, TraceShare: Archive, Archived<TraceShare>: Deserialize<TraceShare, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<DifferentialEvent, __D::Error>

Deserializes using the given deserializer

impl From<BatchEvent> for DifferentialEvent

fn from(batch: BatchEvent) -> Self

Converts to this type from the input type.

impl From<DifferentialEvent> for DifferentialEvent

fn from(event: RawDifferentialEvent) -> Self

Converts to this type from the input type.

impl From<DifferentialEvent> for DifferentialEvent

fn from(event: DifferentialEvent) -> Self

Converts to this type from the input type.

impl From<MergeEvent> for DifferentialEvent

fn from(merge: MergeEvent) -> Self

Converts to this type from the input type.

impl From<MergeShortfall> for DifferentialEvent

fn from(shortfall: MergeShortfall) -> Self

Converts to this type from the input type.

impl From<TraceShare> for DifferentialEvent

fn from(share: TraceShare) -> Self

Converts to this type from the input type.

impl Hash for DifferentialEvent

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 Ord for DifferentialEvent

fn cmp(&self, other: &DifferentialEvent) -> 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,

Restrict a value to a certain interval.

impl PartialEq for DifferentialEvent

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

fn partial_cmp(&self, other: &DifferentialEvent) -> 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<__S: Fallible + ?Sized> Serialize<__S> for DifferentialEvent

where BatchEvent: Serialize<__S>, MergeEvent: Serialize<__S>, DropEvent: Serialize<__S>, MergeShortfall: Serialize<__S>, TraceShare: Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>
