Struct Recorder 

pub struct Recorder { /* private fields */ }

Session-scoped counter storage.

One per ProxySession, shared by that session’s forwarding tasks through Arc (ForwardCtx is #[derive(Clone)] and cloned per task, session.rs:191-229), so concurrently running sessions in one test binary cannot see each other’s increments. That is what makes objects_elided == 0 assertable at all.

Storage is atomics plus a [AtomicU32; 128] histogram — 512 bytes per session. A release sample costs four relaxed atomic operations (sum, count, max, one bucket) on a path that already did a write_all; every other counter costs one.

Implementations

impl Recorder

pub fn new() -> Self

A recorder with every counter at zero.

pub fn snapshot(&self) -> Counters

Snapshot every counter for this session.

Trait Implementations

impl Debug for Recorder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Prints the snapshot, not 128 histogram slots.

impl Default for Recorder

fn default() -> Self

Returns the “default value” for a type.
