nlohmann::byte_container_with_subtype¶

template<typename BinaryType>
class byte_container_with_subtype : public BinaryType;

This type extends the template parameter BinaryType provided to basic_json with a subtype used by BSON and MessagePack. This type exists so that the user does not have to specify a type themselves with a specific naming scheme in order to override the binary type.

Template parameters¶

BinaryType

container to store bytes (std::vector<std::uint8_t> by default)

Member types¶

• container_type - the type of the underlying container (BinaryType)
• subtype_type - the type of the subtype (std::uint64_t)

Member functions¶

• (constructor)
• operator== - comparison: equal
• operator!= - comparison: not equal
• set_subtype - sets the binary subtype
• subtype - return the binary subtype
• has_subtype - return whether the value has a subtype
• clear_subtype - clears the binary subtype

Version history¶

• Added in version 3.8.0.
• Changed type of subtypes to std::uint64_t in 3.10.0.
