inlinenoexcept

move constructor

Move constructor. Constructs a JSON value with the contents of the given value other using move semantics. It "steals" the resources from other and leaves it as JSON null value.

Parameters

[in,out]

other

value to move to this object

Postcondition

*this has the same value as other before the call.

other is a JSON null value.

@complexity Constant.

@exceptionsafety No-throw guarantee: this constructor never throws exceptions.

@requirement This function helps basic_json satisfying the MoveConstructible requirements.

@liveexample{The code below shows the move constructor explicitly called via std::move.,basic_json__moveconstructor}
