import { type Unwrap } from './types.mjs';
/**
 * Unwraps an `Optional`, returning the contained value or a default value if
 * it's `None`.
 *
 * Supports both direct usage and curried form for functional composition.
 * This is often preferred over `unwrap()` when you have a sensible fallback
 * value.
 *
 * @example
 *
 * ```ts
 * const withValue = Optional.some(5);
 *
 * const withoutValue = Optional.none as Optional<number>;
 *
 * assert.isTrue(Optional.unwrapOr(withValue, 0) === 5);
 *
 * assert.isTrue(Optional.unwrapOr(withoutValue, 0) === 0);
 *
 * const unwrapWithDefault = Optional.unwrapOr(10);
 *
 * assert.isTrue(unwrapWithDefault(Optional.some(3)) === 3);
 *
 * assert.isTrue(unwrapWithDefault(Optional.none) === 10);
 * ```
 *
 * @template O The `UnknownOptional` type to unwrap.
 * @template D The type of the default value.
 * @param optional The `Optional` to unwrap.
 * @param defaultValue The value to return if `optional` is `None`.
 * @returns The contained value if `Some`, otherwise `defaultValue`.
