Struct flowcore::model::metrics::Metrics

pub struct Metrics { /* private fields */ }

Metrics stacks a number of statistics on flow execution while being executed

Implementations

impl Metrics

pub fn new(num_functions: usize) -> Self

Create a new Metrics struct

pub fn reset(&mut self)

Reset the values of a Metrics struct back to their initial values

pub fn set_jobs_created(&mut self, jobs: usize)

Set the number of jobs created in Metrics to the jobs value

pub fn increment_outputs_sent(&mut self)

Increment the tracker for the number of output values sent between functions

pub fn track_max_jobs(&mut self, jobs_running: usize)

Keep track of the maximum jobs that are executing in parallel during a flows execution, as a measure of the maximum level of parallelism achieved

pub fn default_start_time() -> Instant

Return the start time for flow execution - used for tracking wall-clock time for the execution

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Metrics

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Metrics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Metrics

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

Formats the value using the given formatter.

impl PartialEq<Metrics> for Metrics

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

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

Serialize this value into the given Serde serializer.
