nrf_edgeai_obsv_encode_cbor()

size_t nrf_edgeai_obsv_encode_cbor	(	nrf_edgeai_obsv_core_t *	state,
		uint8_t *	buf,
		size_t	max_len )

#include <lib/nrf_edgeai_obsv/nrf_edgeai_obsv_encode.h>

Encode observability state and metrics as CBOR (no mutex).

Wire format is defined in obsv.cddl. On Zephyr, prefer Observability CBOR encoding (buffer sizing) on nrf_edgeai_obsv_ctx_t* so the context mutex serializes with inference.

Parameters

state	Initialized portable state with registered metrics.
buf	Output buffer.
max_len	Size of buf.

Returns

Encoded byte count on success, 0 on encoding failure or overflow.

Note

Every registered metric is emitted. The required buffer size depends on the registered metrics and their Kconfig dimensions; custom or larger snapshots need a correspondingly larger buf and max_len.
