/**
|
|
* Helper type to introduce new branded types.
|
|
*
|
|
* `Base` is the underlying data type and `Tag` must be unique symbol/string.
|
|
*
|
|
* Usage:
|
|
* ```ts
|
|
* type LineNumber = Brand<number, "LineNumber">;
|
|
* type RawUrl = Brand<string, "RawUrl">;
|
|
* ```
|
|
*
|
|
* We purposefully use the string index of `_tag` rather then creating a Symbol
|
|
* wrapper that would hide if in IDEs and fail build. This means that at build
|
|
* time if one uses `<branded-var>._tag`, it will build without error and have
|
|
* potentially having a runtime error. This allows us to have multiple places
|
|
* where we define the brands and they will overlap. Also a use case for reusing
|
|
* the type in other downstream projects is simplified.
