Struct Metrics 

pub struct Metrics {
    pub active_threads: usize,
    pub input_channel_len: usize,
    pub input_channel_capacity: Option<usize>,
    pub output_channel_len: usize,
    pub output_channel_capacity: Option<usize>,
    pub execution_count: usize,
    pub average_execution_duration_ns: usize,
}

Struct containing thread pool metrics, that is updated every approx. every 10 seconds.

Fields

active_threads: usize

Current number of running threads, which may temporarily differ from ThreadPool::get_pool_size.

input_channel_len: usize

input_channel_capacity: Option<usize>

output_channel_len: usize

output_channel_capacity: Option<usize>

execution_count: usize

Total executions of the provided function since the last metrics update. Inputs that have been executed on, but not sent are not counted until they have sent;

average_execution_duration_ns: usize

Average nano-second execution duration of the provided function since the last metrics update. Does not include any time the input/output spends in the channels.

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Metrics

fn default() -> Metrics

Returns the “default value” for a type.

impl Copy for Metrics
