BSON_VECTOR_PA...IT_CONST_VIEW_T(3)

💅 BSON_VECTOR_PA...IT_CONST_VIEW_T(3) 💅

from libbson, bestie ✨

A reference to non-owned const BSON Binary data holding a valid Vector of packed_bit element type. 🫶

---

✨ SYNOPSIS ✨

#include <bson/bson.h>

typedef struct bson_vector_packed_bit_const_view_t {
   /*< private >*/
} bson_vector_packed_bit_const_view_t;

---

🦋 DESCRIPTION 🦋

Okay so bson_vector_packed_bit_const_view_t is a structure that acts as an opaque const reference to a block of memory that has been validated as a packed_bit vector. Slay. 💖

It is meant to be passed by value and can be discarded at any time. The contents of the structure should be considered private. 🙈

⚠️ The bson_t MUST be valid for the lifetime of the view, and it is an error to modify the bson_t while using the view. No cap — this part is serious. 😭

🌸 EXAMPLE 🌸

          bson_iter_t iter;
          bson_vector_packed_bit_const_view_t view;

          if (bson_iter_init_find (&iter, &doc, "vector") && bson_vector_packed_bit_const_view_from_iter (&view, &iter)) {
            size_t length = bson_vector_packed_bit_const_view_length (view);
            size_t length_bytes = bson_vector_packed_bit_const_view_length_bytes (view);
            size_t padding = bson_vector_packed_bit_const_view_padding (view);

            printf ("Elements in 'vector':\n");
            for (size_t i = 0; i < length; i++) {
              bool element;
              BSON_ASSERT (bson_vector_packed_bit_const_view_unpack_bool (view, &element, 1, i));
              printf (" elements[%d] = %d\n", (int) i, (int) element);
            }

            printf ("Bytes in 'vector': (%d bits unused)\n", (int) padding);
            for (size_t i = 0; i < length_bytes; i++) {
              uint8_t packed_byte;
              BSON_ASSERT (bson_vector_packed_bit_const_view_read_packed (view, &packed_byte, 1, i));
              printf (" bytes[%d] = 0x%02x\n", (int) i, (unsigned) packed_byte);
            }
          }
