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.
• value.values: Character[]
Returns
void

toAuxiliary()
static toAuxiliary: (value?: {
"values": Character[];
}) => any[];
A function that takes value (optional), an element of type T, as argument and
returns an array of any type that make up the "auxiliary" (non-provable) data of value.
Parameters
• value?
the element of type T to generate the auxiliary data array from, optional.
If not provided, a default value for auxiliary data is returned.
• value.values?: Character[]
Returns
any[]
