NRF_EDGEAI_OBSV_ENCODE_METRIC_SIZE

#define NRF_EDGEAI_OBSV_ENCODE_METRIC_SIZE	(		n_rows,
			n_cols )

#include <include/nrf_edgeai_obsv/nrf_edgeai_obsv_encode_sizes.h>

Value:

        (_NRF_EDGEAI_OBSV_ENCODE_METRIC_BLOCK_FIXED +                   \
         (n_rows) * (_NRF_EDGEAI_OBSV_ENCODE_TABLE_ROW_FIXED +          \
                     (n_cols) * _NRF_EDGEAI_OBSV_ENCODE_UINT32_WORST))

CBOR encoded size budget for one custom metric.

Computes the worst-case encoded size (bytes) for a single metric whose snapshot() returns n_rows rows and n_cols columns of uint32_t counters. Use this to determine how many extra bytes are needed in the encode buffer for a custom metric, and set CONFIG_NRF_EDGEAI_OBSV_EXTRA_ENCODE_BYTES to the sum across all custom metrics. Optionally guard the value with a BUILD_ASSERT:

BUILD_ASSERT(CONFIG_NRF_EDGEAI_OBSV_EXTRA_ENCODE_BYTES >=
             NRF_EDGEAI_OBSV_ENCODE_METRIC_SIZE(MY_ROWS, MY_COLS),
             "EXTRA_ENCODE_BYTES too small for custom metric");

Parameters

n_rows	Number of rows in the counter matrix (num_rows from snapshot).
n_cols	Number of columns in the counter matrix (num_cols from snapshot).
