Enum Visibility 

#[non_exhaustive]
pub enum Visibility {
    Visible,
    Hidden,
    Unknown,
}

What a session knows about whether a visitor can follow a link.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Visible

The rendered link has a usable area and is not hidden or clipped.

Hidden

Attributes, styles or layout hide the link.

Unknown

The session cannot establish visibility, e.g. without CSS and layout.
