}

Telemetry buffer (64 bytes, cache-line aligned).

This structure is updated by the GPU kernel and read by the host for monitoring and debugging purposes.

Fields

messages_processed: u64

Total messages processed successfully.

messages_dropped: u64

Total messages dropped (queue full, timeout, etc.).

total_latency_us: u64

Sum of processing latencies in microseconds.

min_latency_us: u64

Minimum processing latency in microseconds.

max_latency_us: u64

Maximum processing latency in microseconds.

input_queue_depth: u32

Current input queue depth.

output_queue_depth: u32

Current output queue depth.

last_error: u32

Last error code (0 = no error).

_reserved: [u32; 3]

Reserved for alignment (pad to 64 bytes).

Implementations

impl TelemetryBuffer

pub const fn new() -> TelemetryBuffer
