Struct StepMetrics 

pub struct StepMetrics {
    pub total_us: u64,
    pub command_processing_us: u64,
    pub propagator_us: Vec<(String, u64)>,
    pub snapshot_publish_us: u64,
    pub memory_bytes: usize,
}

Timing and memory metrics collected during a single tick.

All durations are in microseconds. The engine populates these fields after each step() call; consumers (telemetry, backoff logic) read them from the most recent tick.

Fields

total_us: u64

Wall-clock time for the entire tick, in microseconds.

command_processing_us: u64

Time spent processing the ingress command queue, in microseconds.

propagator_us: Vec<(String, u64)>

Per-propagator execution times: (name, microseconds).

snapshot_publish_us: u64

Time spent publishing the snapshot to the ring buffer, in microseconds.

memory_bytes: usize

Memory usage of the arena after the tick, in bytes.
