check()

static check: (value: {
"values": Character[];
}) => void;

Add assertions to the proof to check if value is a valid member of type T. This function does not return anything, instead it creates any number of assertions to prove that value is a valid member of the type T.

For instance, calling check function on the type Bool asserts that the value of the element is either 1 or 0.

Parameters

value

the element of type T to put assertions on.

void

toAuxiliary()

static toAuxiliary: (value?: {
