Struct titanium::desktop::gui::libdruid::text::ParseFormatter

#[non_exhaustive]
pub struct ParseFormatter<T> { /* private fields */ }

A naive Formatter for types that implement FromStr.

For types that implement std::fmt::Display, the ParseFormatter::new constructor creates a formatter that format’s its value using that trait. If you would like to customize the formatting, you can use the ParseFormatter::with_format_fn constructor, and pass your own formatting function.
