Reset-global-style-tag-registry

Reset the shared global StyleTagRegistry back to the library default. This helper is useful after temporary global overrides in tests or boot code.

Interface

pub fn reset_global_style_tag_registry() -> Unit {

Explanation

Detailed rules explaining key parameters and behaviors

• This helper restores the shared global registry to the built-in default tag set.
• It is the simplest cleanup path after temporary global registry customization.
• Local formatter registries remain unaffected because they are not sourced from the shared global registry.

How to Use

Here are some specific examples provided.

When Need To Undo Temporary Global Overrides

When tests or boot code changed the shared registry and want the default back:

set_global_style_tag_registry(style_tag_registry().set_tag("accent", fg=Some("#123456")))
reset_global_style_tag_registry()

In this example, subsequent formatters without local registries return to the library default global tag set.

Error Case

e.g.:

• If a formatter already carries local tags, resetting the global registry does not change that formatter's local tag behavior.

• This helper only resets shared global formatter state; it does not alter serialized formatter configs.

Notes

1. This is the cleanup helper paired with set_global_style_tag_registry(...).

2. It is especially useful in tests that temporarily customize shared style behavior.
