pub struct PrettyOptionDisplay<T>(pub Option<T>)
where
T: Display;Expand description
Helper struct that provides a nicer format for Debug printing Option by dropping the
Some(...) that wraps its value, and instead uses the Display trait implementation of the
value.
Examples:
"MyStruct { option_string_field: None }"
"MyStruct { option_string_field: "string field value" }"
