Enum ExchangeError 

pub enum ExchangeError {
    TxTimeout,
    RxTimeout,
    AckTimeout {
        reply: u8,
    },
    AckStuck {
        reply: u8,
    },
}

Why one byte exchange failed.

Variants

TxTimeout

The port never became ready to take the byte.

RxTimeout

The byte shifted out but no reply came back.

AckTimeout

The reply came back and the device never pulsed /ACK; the reply is kept because an absent device answers 0xFF here.

Fields

reply: u8

The byte received before the wait.

AckStuck

The device pulsed /ACK but held it asserted.

Fields

reply: u8

The byte received before the wait.

Trait Implementations

impl Clone for ExchangeError

fn clone(&self) -> ExchangeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExchangeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ExchangeError

fn eq(&self, other: &ExchangeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
