</code></pre></div> <p>This type is a type designed to carry binary data that appears in various serialized formats, such as <abbr title="Concise Binary Object Representation">CBOR</abbr>'s Major Type 2, MessagePack's bin, and <abbr title="Binary JSON">BSON</abbr>'s generic binary subtype. This type is NOT a part of standard <abbr title="JavaScript Object Notation">JSON</abbr> and exists solely for compatibility with these binary types. As such, it is simply defined as an ordered sequence of zero or more byte values.</p> <p>Additionally, as an implementation detail, the subtype of the binary data is carried around as a <code>std::uint64_t</code>, which is compatible with both of the binary data formats that use binary subtyping, (though the specific numbering is incompatible with each other, and it is up to the user to translate between them). The subtype is added to <code>BinaryType</code> via the helper type <a href=../../byte_container_with_subtype/ >byte_container_with_subtype</a>.</p> <p><a href="https://tools.ietf.org/html/rfc7049"><abbr title="Concise Binary Object Representation">CBOR</abbr>'s <abbr title="Request for Comments">RFC</abbr> 7049</a> describes this type as:</p> <blockquote> <p>Major type 2: a byte string.
