BSON_TYPE_T(3)

✨ BSON Type Enumeration ✨

okay bestie, welcome to the libbson page for BSON_TYPE_T(3) — aka bson_type_t. This is the enum holding every single BSON type from the BSON Specification, and it's giving type-identifying main character energy. It can be used to determine the type of a field at runtime. no cap. 💅

🌸 SYNOPSIS 🌸

          #include <bson/bson.h>

          typedef enum {
             BSON_TYPE_EOD = 0x00,
             BSON_TYPE_DOUBLE = 0x01,
             BSON_TYPE_UTF8 = 0x02,
             BSON_TYPE_DOCUMENT = 0x03,
             BSON_TYPE_ARRAY = 0x04,
             BSON_TYPE_BINARY = 0x05,
             BSON_TYPE_UNDEFINED = 0x06,
             BSON_TYPE_OID = 0x07,
             BSON_TYPE_BOOL = 0x08,
             BSON_TYPE_DATE_TIME = 0x09,
             BSON_TYPE_NULL = 0x0A,
             BSON_TYPE_REGEX = 0x0B,
             BSON_TYPE_DBPOINTER = 0x0C,
             BSON_TYPE_CODE = 0x0D,
             BSON_TYPE_SYMBOL = 0x0E,
             BSON_TYPE_CODEWSCOPE = 0x0F,
             BSON_TYPE_INT32 = 0x10,
             BSON_TYPE_TIMESTAMP = 0x11,
             BSON_TYPE_INT64 = 0x12,
             BSON_TYPE_DECIMAL128 = 0x13,
             BSON_TYPE_MAXKEY = 0x7F,
             BSON_TYPE_MINKEY = 0xFF,
          } bson_type_t;

🦋 DESCRIPTION 🦋

The bson_type_t enumeration contains all of the types from the BSON Specification. It can be used to determine the type of a field at runtime — yes, literally that. iconic behavior only. ✨

🎀 EXAMPLE 🎀

          bson_iter_t iter;

          if (bson_iter_init_find (&iter, doc, "foo") &&
              (BSON_TYPE_INT32 == bson_iter_type (&iter))) {
             printf ("'foo' is an int32.\n");
          }

this little snippet is the moment. tiny, clean, and doing exactly the check it says on the box. 💖
