Enum ActivityType

pub enum ActivityType {
    Scheduling = 0,
    Processing = 2,
    Spinning = 1,
    Serialization = 3,
    Deserialization = 4,
    ControlMessage = 5,
    DataMessage = 6,
    Waiting = 8,
    Busy = 9,
}

The various types of activity that can happen in a dataflow. Unknown et al. shouldn’t be emitted by instrumentation. Instead, they might be inserted as helpers during PAG construction.

Variants

Scheduling = 0

Operator scheduled. Used as temporary state for LogRecords where it’s still unclear whether they were only spinning or also did some work

Processing = 2

Operator actually doing work

Spinning = 1

Operator scheduled, but not doing any work

Serialization = 3

Data serialization

Deserialization = 4

Data deserialization

ControlMessage = 5

remote control messages, e.g. about progress

DataMessage = 6

remote data messages, e.g. moving tuples around

Waiting = 8

Waiting for unblocking. In particular, operator might wait for external input. (not emitted by profiling)

Busy = 9

Waiting where next activity is actively prepared, e.g. in-between a ScheduleEnd and consecutive ScheduleStart. In particular, operator doesn’t depend on external input. (not emitted by profiling)

Trait Implementations

impl Abomonation for ActivityType

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 ActivityType

fn clone(&self) -> ActivityType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivityType

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

Formats the value using the given formatter.

impl Hash for ActivityType

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 ActivityType

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

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

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