Variants

InvalidArgument

One or more of the supplied arguments are not valid for the given operation.

OutOfSpace

There is not enough space in the given buffer to complete the operation.

ParseFailure

An error was encountered while attempting to parse the data.

ResponseTimeout

Operation timed out waiting for a response.

BadResponse

The response was well-formed, but not appropriate for the given request.

UnknownMessageCode

The [message code][async-coap::message::MsgCode] was not recognized by this version of rust-async-coap.

UnhandledCriticalOption

A critical option present in the message was not supported.

IOError

An I/O error occurred while performing this operation.

Cancelled

This operation has been cancelled.

HostNotFound

Unable to look up the given host because it was not found.

HostLookupFailure

Unable to look up the given host for an unspecified reason.

ResourceNotFound

The response indicated that the given resource was not found.

Unauthorized

The response indicated that the request was unauthorized.

Forbidden

The response indicated that the request was forbidden.

ClientRequestError

The response indicated an unspecified client error.

ServerError

The response indicated an unspecified server error.

Reset

The transaction was reset.

Trait Implementations

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Default for Error

fn default() -> Self

Returns the “default value” for a type.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Extend<Result<(), Error>> for Error

fn extend<T: IntoIterator<Item = Result<(), Error>>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl From<Error> for Error

Available on crate feature std only.

fn from(_: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(_: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(_err: Error) -> Self

Converts to this type from the input type.

impl From<ErrorLinkFormat> for Error

fn from(_: ErrorLinkFormat) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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