make_callback_var()

template<typename T , typename F >

var_value< plain_type_t< T > > stan::math::make_callback_var ( T &&  value, F &&  functor  )

inline

Creates a new var initialized with a callback_vari with a given value and reverse-pass callback functor.

The callback functor will be passed a reference to the constructed vari.

All captured values must be trivially destructible or they will leak memory. to_arena() function can be used to ensure that.

Template Parameters

T	type of value
F	type of callable

Parameters

value	value of the vari
functor	functor or other callable to call in the reverse pass
