Enum UsbSerialError 

pub enum UsbSerialError {
    Unsupported(String),
    Io(String),
    TimedOut,
    Disconnected,
    Cancelled,
    ProbeFailed(String),
}

High-level driver / transport failure.

Variants

Unsupported(String)

Operation or chip feature not supported.

Io(String)

I/O or USB transfer failure (including stall mapped to a message).

TimedOut

Transfer timed out.

Disconnected

Device unplugged or USB link lost (bulk IN detach / EPROTO, etc.).

Cancelled

Transfer cancelled by the host.

ProbeFailed(String)

Could not identify / open a suitable driver.

Trait Implementations

impl Clone for UsbSerialError

fn clone(&self) -> UsbSerialError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsbSerialError

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

Formats the value using the given formatter.

impl Display for UsbSerialError

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

Formats the value using the given formatter.

impl Eq for UsbSerialError

impl Error for UsbSerialError

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<TransferError> for UsbSerialError

fn from(value: TransferError) -> Self

Converts to this type from the input type.

impl PartialEq for UsbSerialError

fn eq(&self, other: &UsbSerialError) -> 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.
