Function: parseCalldataField()

parseCalldataField(__namedParameters): string | string[]

Defined in: src/utils/calldata/requestParser.ts:412

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

Parameters

__namedParameters

argsIterator

Iterator<any>

Iterator for value of the field

input

AbiEntry

input(field) information from the abi that will be used to parse the data

structs

AbiStructs

structs from abi

enums

AbiEnums

enums from abi

parser

AbiParserInterface

parser used to serialize the value

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']
