name: duk_cbor_encode
|
|
|
|
proto: |
|
|
void duk_cbor_encode(duk_context *ctx, duk_idx_t idx, duk_uint_t encode_flags);
|
|
|
|
stack: |
|
|
[ ... val! ... ] -> [ ... cbor_val! ... ]
|
|
|
|
summary: |
|
|
<p>Encodes an arbitrary value into its CBOR representation as an in-place
|
|
operation. The resulting value is an ArrayBuffer (for now). No flags are
|
|
defined at present, so pass in a <code>0</code> for flags.</p>
|
|
|
|
<div class="note">
|
|
Mapping from ECMAScript values to CBOR is experimental and the encoding
|
|
result may change over time. For example, custom CBOR tags will be added
|
|
to improve encode-decode roundtripping of ECMAScript values. Also the
|
|
result type (ArrayBuffer) may change later.

example: |
|
|
unsigned char *buf;
|
|
duk_size_t len;
|
|
|
|
duk_push_object(ctx);
|
|
duk_push_int(ctx, 42);
|
|
duk_put_prop_string(ctx, -2, "meaningOfLife");
|
|
duk_cbor_encode(ctx, -1, 0);
|
|
buf = duk_require_buffer_data(ctx, -1, &len);
|
|
/* CBOR data is in buf[0] ... buf[len - 1]. */
|
|
duk_pop(ctx);
