What the bridge refused, or answered wrongly.

Variants

WrongAnswer

The bridge answered a different order than the one sent.

Fields

asked: u8

What was asked.

answered: u8

What came back.

Short

The answer is shorter than that order’s answer is.

Fields

got: usize

How many bytes came back.

needs: usize

How many the answer needs.

Refused

A pin write or a reset did not take.

Fields

status: u8

The status the bridge gave.

Transfer

One SPI entry in a bulk order failed.

Fields

id: u8

Which entry.

status: u8

How, as the bridge reports it: 1 failed, 2 a wrong parameter, 3 a timeout.

UnknownEntry

An SPI entry in the answer is not one of the two kinds.

Fields

id: u8

Which entry.

kind: u8

What kind it claimed to be.

TooMany

A bulk order holds more than the bridge takes.

Trait Implementations

impl Clone for BridgeError

fn clone(&self) -> BridgeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BridgeError

impl Debug for BridgeError

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

Formats the value using the given formatter.

impl Eq for BridgeError

impl Error for BridgeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<BridgeError> for UsbError

fn from(error: BridgeError) -> UsbError

Converts to this type from the input type.

impl PartialEq for BridgeError

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

Equality operator ==.

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

Inequality operator !=.
