lecp_construct() - Construct an LECP parser context

Parameters

ctx	the parser context object to be initialized
cb	the user callback to receive the parsing events
user	an opaque user pointer available at cb
paths	an optional array of parsing paths
paths_count	how many paths in paths

Prepares an LECP parser context for parsing.

lecp_destruct()

lecp_destruct() - Destroys an LECP parser context

Parameters

lecp_parse()

LWS_VISIBLE LWS_EXTERN int lecp_parse	(	struct lecp_ctx *	ctx,
		const uint8_t *	cbor,
		size_t	len )

lecp_parse() - parses a chunk of input CBOR

ctx: the parsing context cbor: the start of the chunk of CBOR len: the number of bytes of CBOR available at cbor

Returns LECP_CONTINUE if more input needed, one of enum lecp_reasons for a fatal error, else 0 for successful parsing completion.

On success or _CONTINUE, ctx->used_in is set to the number of input bytes consumed.

lecp_parse_report_raw()

LWS_VISIBLE LWS_EXTERN void lecp_parse_report_raw	(	struct lecp_ctx *	ctx,
		int	on )

lecp_parse_report_raw() - turn cbor raw reporting on and off

Parameters

ctx	the lecp context
on	0 to disable (defaults disabled), 1 to enable

For cose_sign, it needs access to raw cbor subtrees for the hash input. This api causes LECPCB_LITERAL_CBOR parse callbacks when there are ctx->cbor_pos bytes of raw cbor available in ctx->cbor[]. the callbacks occur when the ctx->cbor[] buffer fills or if it holds anything when this spi is used to stop the reports.

The same CBOR that is being captured continues to be passed for parsing.

lecp_parse_map_is_key()

LWS_VISIBLE LWS_EXTERN int lecp_parse_map_is_key

(

struct lecp_ctx *

ctx

)

lecp_parse_map_is_key() - return nonzero if we're in a map and this is a key

Parameters

ctx	the lwcp context

Checks if the current value is a key in a map, ie, that you are on a "key" in a list of "{key: value}" pairs. Zero means you're either not in a map or not on the key part, and nonzero means you are in a map and on a key part.
