A collection of HTTP errors and utilities.

The export errors contains an individual class that extends HttpError which makes handling HTTP errors in a structured way.

The function createHttpError provides a way to create instances of errors in a factory pattern.

The function isHttpError is a type guard that will narrow a value to an HttpError instance.
