Enum HostError 

#[non_exhaustive]
pub enum HostError {
    PipeError(PipeError),
    RequestFailed,
    InvalidDescriptor,
    OutOfSlots,
    OutOfPipes,
    NoSuchDevice,
    InsufficientMemory,
    Other(&'static str),
}

Indicates type of error of Host interface

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PipeError(PipeError)

A pipe-level transfer error occurred.

RequestFailed

The control request was not acknowledged by the device.

InvalidDescriptor

A descriptor returned by the device could not be parsed.

OutOfSlots

No free device slots available.

OutOfPipes

No free host pipes available.

NoSuchDevice

The addressed device does not exist.

InsufficientMemory

Insufficient memory for the requested operation.

Other(&'static str)

An unspecified error with a static description.

Trait Implementations

impl Clone for HostError

fn clone(&self) -> HostError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostError

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

Formats the value using the given formatter.

impl Format for HostError

where PipeError: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<PipeError> for HostError

fn from(value: PipeError) -> Self

Converts to this type from the input type.

impl PartialEq for HostError

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