Trait Flatten 

pub trait Flatten {
    // Required method
    fn flatten(&self, buffer: &mut impl MetricBuffer);
}

Allows a type to emit its telemetry representation as key-value pairs into a MetricBuffer.

Each call to flatten should write one or more entries into the buffer, where each entry is a static key and a Value.

For primitive types (e.g. u8, f32, bool), a default implementation is provided that emits a single "value" key. Composite types should implement this trait to emit one entry per field. Types that do not produce telemetry can provide an empty implementation.

Required Methods

fn flatten(&self, buffer: &mut impl MetricBuffer)

Writes telemetry key-value pairs into the given buffer.

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.
