Struct Display2Format

pub struct Display2Format<'a, T: Display + ?Sized>(pub &'a T);

An “adapter” type to feed Display values into defmt macros, which expect defmt::Format values.

This adapter disables compression and uses the core::fmt code on-device! You should prefer defmt::Format over Display whenever possible.

Examples

defmt::info!("{}", defmt::Display2Format(&expensive_thing));
//                                        ˆˆˆˆˆˆˆˆˆˆˆˆˆˆˆ
//                                        must implement `fmt::Display`

Note that any provided defmt display hints will be ignored because this always uses {} to format the contained value.
