parseCalldataField(argsIterator): string | string[]

Defined in: src/utils/calldata/requestParser.ts:416

Parse one field of the calldata by using input field from the abi for that method

Parameters​

argsIterator​

Iterator for value of the field

argsIterator​

Iterator<any>

input​

AbiEntry

structs​

AbiStructs

enums​

AbiEnums

parser​

AbiParserInterface

Returns​

string | string[]

  • parsed arguments in format that contract is expecting

Example​

const abiEntry = { name: 'test', type: 'struct' };
const abiStructs: AbiStructs = {
 struct: {
   members: [
       {
         name: 'test_name',
         type: 'test_type',
         offset: 1,
       },
   ],
   size: 2,
   name: 'cairo__struct',
   type: 'struct',
  },
};

const abiEnums: AbiEnums = {
  enum: {
    variants: [
      {
        name: 'test_name',
        type: 'cairo_struct_variant',
        offset: 1,
      },
    ],
    size: 2,
    name: 'test_cairo',
    type: 'enum',
  },
};

const args = [{ test_name: 'test' }];
const argsIterator = args[Symbol.iterator]();
const parsedField = parseCalldataField(
  argsIterator,
  abiEntry,
  abiStructs,
  abiEnums
);
// parsedField === ['1952805748']
