The instance_function module exposes a way to declaratively instance a generic function with particular set of types.

All functions and symbols are in "instance_function" module, use require to get access to it.

require daslib/instance_function

.. das:attribute:: instance_function

[instance_function(generic_name,type1=type1r,type2=type2r,...)] macro creates instance of the generic function with a particular set of types. In the followin example body of the function inst will be replaced with body of the function print_zero with type int:

def print_zero ( a : auto(TT) )
    print("{[[TT]]}\n")
[export, instance_function(print_zero,TT="int")]
def inst {}
