method

function method<K, T>(
   target: T & { [k in string]: (args: any) => Promise<void> }, 
   methodName: K & string & keyof T, 
   descriptor: PropertyDescriptor, 
   returnType?: Provable<any>): void

Defined in: lib/mina/v1/zkapp.ts:98

A decorator to use in a zkApp to mark a method as provable. You can use inside your zkApp class as:

\@method async myMethod(someArg: Field) {
  // your code here
}

To return a value from the method, you have to explicitly declare the return type using the method.returns decorator:

\@method.returns(Field)
async myMethod(someArg: Field): Promise<Field> {
  // your code here
}
