pub struct QueryStats { /* private fields */ }
Expand description

Execution statistics of a query.

Implementations§

source§

impl QueryStats

source

pub fn empty() -> Self

source

pub fn num_requests(&self) -> u32

Gets the total number of requests initiated by the query.

source

pub fn num_successes(&self) -> u32

Gets the number of successful requests.

source

pub fn num_failures(&self) -> u32

Gets the number of failed requests.

source

pub fn num_pending(&self) -> u32

Gets the number of pending requests.

Note: A query can finish while still having pending requests, if the termination conditions are already met.

source

pub fn duration(&self) -> Option<Duration>

Gets the duration of the query.

If the query has not yet finished, the duration is measured from the start of the query to the current instant.

If the query did not yet start (i.e. yield the first peer to contact), None is returned.

source

pub fn merge(self, other: QueryStats) -> Self

Merges these stats with the given stats of another query, e.g. to accumulate statistics from a multi-phase query.

Counters are merged cumulatively while the instants for start and end of the queries are taken as the minimum and maximum, respectively.

Trait Implementations§

source§

impl PartialEq for QueryStats

source§

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

1.0.0 · source§

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.
