Enum usbd_serial::UsbError

pub enum UsbError {
    WouldBlock,

    EndpointMemoryOverflow,
    InvalidEndpoint,
    Unsupported,

}

A USB stack error.

Variants

WouldBlock

An operation would block because the device is currently busy or there is no data available.

ParseError

Parsing failed due to invalid input.

BufferOverflow

A buffer too short for the data to read was passed, or provided data cannot fit within length constraints.

EndpointOverflow

Classes attempted to allocate more endpoints than the peripheral supports.

EndpointMemoryOverflow

Classes attempted to allocate more packet buffer memory than the peripheral supports. This can be caused by either a single class trying to allocate a packet buffer larger than the peripheral supports per endpoint, or multiple allocated endpoints together using more memory than the peripheral has available for the buffers.

InvalidEndpoint

The endpoint address is invalid or already used.

Unsupported

Operation is not supported by device or configuration.

InvalidState

Operation is not valid in the current state of the object.

Trait Implementations

impl Clone for UsbError

fn clone(&self) -> UsbError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UsbError

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

Formats the value using the given formatter.

impl PartialEq for UsbError

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

This method tests for self and other values to be equal, and is used by ==.

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

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