inlinestatic

Creates a JSON binary array value from a given binary container. Binary values are part of various binary formats, such as CBOR, MessagePack, and BSON. This constructor is used to create a value for serialization to those formats.

Note
Note, this function exists because of the difficulty in correctly specifying the correct template overload in the standard value ctor, as both JSON arrays and JSON binary arrays are backed with some form of a std::vector. Because JSON binary arrays are a non-standard extension it was decided that it would be best to prevent automatic initialization of a binary array type, for backwards compatibility and so it does not happen on accident.
Parameters
[in]initcontainer containing bytes to use as binary type
Returns
JSON binary array value
Complexity
Linear in the size of init.
Exception safety
Strong guarantee: if an exception is thrown, there are no changes to any JSON value.
Since
version 3.8.0
