/// Because a type can only have one `Display` implementation, it is often preferable
/// to only implement `Display` when there is a single most "obvious" way that
/// values can be formatted as text. This could mean formatting according to the
/// "invariant" culture and "undefined" locale, or it could mean that the type
/// display is designed for a specific culture/locale, such as developer logs.

/// If not all values have a justifiably canonical textual format or if you want
/// to support alternative formats not covered by the standard set of possible
/// [formatting traits], the most flexible approach is display adapters: methods
/// like [`str::escape_default`] or [`Path::display`] which create a wrapper
/// implementing `Display` to output the specific display format.
