Struct defmt::Display2Format
source · pub struct Display2Format<'a, T: Display + ?Sized>(pub &'a T);
Expand description
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.
