check()​

static check: (value: {
  "field": Field;
  "symbol": string;
 }) => 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.field: Field

• value.symbol: string

Returns​

void

fromFields()​

static fromFields: (fields: Field[], aux: any[]) => {
  "field": Field;
  "symbol": string;
};

A function that returns an element of type T from the given provable and "auxiliary" data.

This function is the reverse operation of calling toFields and toAuxilary methods on an element of type T.

Parameters​

• fields: Field[]

an array of Field elements describing the provable data of the new T element.

• aux: any[]

an array of any type describing the "auxiliary" data of the new T element, optional.

Returns​

{
  "field": Field;
  "symbol": string;
}

field: Field;
symbol​
symbol: string;

}

 } & (value: string | {
  "field": Field;
  "symbol": string;
 }) => {
  "field": Field;
  "symbol": string;
};

toAuxiliary()​

static toAuxiliary: (value?: {
  "field": Field;
  "symbol": string;
 }) => 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.field?: Field

• value.symbol?: string

Returns​

any[]

toFields()​

static toFields: (value: {
  "field": Field;

Parameters​
