Struct BusLogger

pub struct BusLogger<W: Write, T>(/* private fields */);

A wrapper around an embedded_hal bus peripheral that traces each read and write call and prints the raw bytes that were sent or received. It will also pretty-print the error result if the underlying request failed.

Currently, this requires that the error type of the underlying peripheral implements std::fmt::Debug, which most of them seem to do.

Implementations

impl<W: Write, T> BusLogger<W, T>

pub fn new(w: W, t: T) -> BusLogger<W, T>

Trait Implementations

where <T as Read>::Error: Debug,

type Error = <T as Read>::Error

Error type

fn read(&mut self, address: u8, buffer: &mut [u8]) -> Result<(), Self::Error>

impl<W: Write, T: WriteRead> WriteRead for BusLogger<W, T>

where <T as WriteRead>::Error: Debug,

type Error = <T as WriteRead>::Error

Error type

fn write_read( &mut self, address: u8, bytes: &[u8], buffer: &mut [u8], ) -> Result<(), Self::Error>
