# DecodedData

> Generic decoded structure from ABI-encoded data

# DecodedData

Generic structure representing decoded values with their corresponding ABI types. Provides type-safe access to decoded contract data.

## Type

```typescript theme={null}
type DecodedDataType<T = unknown> = {
  readonly values: T;
  readonly types: readonly string[];
};
```

## Construction

```typescript theme={null}
import * as DecodedData from '@tevm/voltaire/primitives/DecodedData';

// Single value
const data = DecodedData.from(42n, ["uint256"]);

// Multiple values
const data = DecodedData.from(
  [100n, "0x1234", true],
  ["uint256", "address", "bool"]
);

// Structured data
const data = DecodedData.from(
  { amount: 100n, recipient: "0x..." },
  ["uint256", "address"]
);
```

## Type Safety

```typescript theme={null}
interface TransferData {
  recipient: string;
  amount: bigint;
}

const data = DecodedData.from<TransferData>(
  { recipient: "0x...", amount: 100n },
  ["address", "uint256"]
);

// Type-safe access
const recipient: string = data.values.recipient;
const amount: bigint = data.values.amount;
```

## Example

```typescript theme={null}
import * as DecodedData from '@tevm/voltaire/primitives/DecodedData';

// Function return values
const returnValues = DecodedData.from(
  [1000n, "0x742d35...", true],
  ["uint256", "address", "bool"]
);

console.log("Balance:", returnValues.values[0]);
console.log("Owner:", returnValues.values[1]);
console.log("Active:", returnValues.values[2]);
console.log("Types:", returnValues.types);

// Tuple data
interface UserInfo {
  name: string;
  balance: bigint;
  active: boolean;
}

const userInfo = DecodedData.from<UserInfo>(
  { name: "Alice", balance: 1000n, active: true },
  ["string", "uint256", "bool"]
);
```
