Struct druid::text::format::ParseFormatter

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

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 it's 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.
