Struct MetricsSnapshot 

pub struct MetricsSnapshot {
    pub encode_cycles: u64,
    pub decode_cycles: u64,
    pub encoded_bytes: u32,
    pub decoded_bytes: u32,
    pub sample_count: u32,
}

Per-direction framing metrics accumulated since the last snapshot reset.

Returned by CmdID super::CMD_ID_METRICS (0xFFFE). The target atomically resets all counters when it replies.

Cycle counts are DWT cycle counter deltas (Cortex-M4F @ firmware clock frequency). Convert to wall-clock duration by dividing by the CPU frequency in Hz.

Fields

encode_cycles: u64

Total DWT cycles spent in rzcobs_encode (upstream, target→host).

decode_cycles: u64

Total DWT cycles spent in rzcobs_decode (downstream, host→target).

encoded_bytes: u32

Total payload bytes input to rzcobs_encode (pre-framing size).

decoded_bytes: u32

Total payload bytes output by rzcobs_decode (post-unframe size).

sample_count: u32

Number of complete request/response round trips counted.
