Hex

ariel_os::debug::log

Struct Hex 

pub struct Hex<T>(pub T)
where
    T: AsRef<[u8]>;
Expand description

A newtype around byte slices used for all of Ariel OS’s logging facades that turns the bytes into some hex output.

Its preferred output is 00 11 22 33, but log facades may also produce something like [00, 11, 22, 33] (eg. while that is cheaper on defmt).

Instead of writing some variation of info!("Found bytes {:02x}", data), you can write info!("Found bytes {}", Hex(data)).
