Std.App.Metrics.Recording

trait

This declaration names behavior that types can implement.

What it does

What a program measured, recorded one value at a time.

A request records several things about itself, and as methods they read in

the order they are measured rather than inside out. Every one of these

answers a whole registry, so the value recorded last is the outermost call

when they are written as functions — which is the reverse of the order the

program measured them in.

A metric nothing declared is not measured and is not an error: a module

reporting something the program did not declare should not be able to stop

it, and the absence is visible in what is rendered.
