Struct defmt::Debug2Format

source ·
pub struct Debug2Format<'a, T: Debug + ?Sized>(pub &'a T);
Expand description

An “adapter” type to feed Debug 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 Debug whenever possible.

§Examples

defmt::info!("{:?}", defmt::Debug2Format(&expensive_thing));
//                                        ˆˆˆˆˆˆˆˆˆˆˆˆˆˆˆ
//                                        must `#[derive(Debug)]`

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