Trait Source 

pub trait Source {
    // Required method
    fn sample_metrics<S: Sampler>(&self, sampler: S);

    // Provided method
    fn and_sample<U>(self, other: U) -> And<Self, U>
       where Self: Sized { ... }
}

A source of Metrics.

Required Methods

fn sample_metrics<S: Sampler>(&self, sampler: S)

Produce a current sample for all metrics in the source.

Provided Methods

fn and_sample<U>(self, other: U) -> And<Self, U>

where Self: Sized,

Chain this source to other, sampling metrics from both.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
