Struct libp2p::kad::QueryStats[−][src]

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

Execution statistics of a query.

Implementations

impl QueryStats[src]

pub fn empty() -> QueryStats[src]

pub fn num_requests(&self) -> u32[src]

Gets the total number of requests initiated by the query.

pub fn num_successes(&self) -> u32[src]

Gets the number of successful requests.

pub fn num_failures(&self) -> u32[src]

Gets the number of failed requests.

pub fn num_pending(&self) -> u32[src]

Gets the number of pending requests.

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

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

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.

pub fn merge(self, other: QueryStats) -> QueryStats[src]

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.
