Type Alias Result<T, E>

Result: Success<T> | Failure<E>

Represents the result of an operation that can succeed or fail.

Result is a type-safe way to handle errors without throwing exceptions. It forces explicit error handling at compile time.

Type Parameters

T
The type of the success value
E extends Error = Error
The type of the error (must extend Error)

Example

function divide(a: number, b: number): Result<number, DomainError> {
  if (b === 0) {
    return Failure.create(new DomainError('DIVISION_BY_ZERO', 'Cannot divide by zero'));
  }
  return Success.create(a / b);
}

const result = divide(10, 2);
if (result.isSuccess) {
  console.log(result.value); // 5
} else {
  console.error(result.error.message);
}
