       BSON_TYPE_DOCUMENT = 0x03,
       BSON_TYPE_ARRAY = 0x04,

       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_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.

## Functions

## 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");
    }
