    Custom(Box<dyn FluentType + Send>),
    None,
    Error,
}
Expand description

The FluentValue enum represents values which can be formatted to a String.

Those values are either passed as arguments to FluentBundle::format_pattern or produced by functions, or generated in the process of pattern resolution.
