Enum Error

#[non_exhaustive]
pub enum Error {
    NoPacketInfo,
    Ipv6NotImplemented,
    NotImplemented,
    Syscall(Syscall, Error),
    SmoltcpMulticast(Syscall, MulticastError),
    SmoltcpUdpSend(SendError),
}

The errors which can be returned from UDP trait methods

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.

NoPacketInfo

recvmsg didn’t return packet info as expected

Ipv6NotImplemented

IPv6 attempted (NYI)

NotImplemented

Something else not implemented

Syscall(Syscall, Error)

Available on crate feature std only.

A system call returned an error

SmoltcpMulticast(Syscall, MulticastError)

Available on crate feature smoltcp only.

A smoltcp multicast call returned an error

SmoltcpUdpSend(SendError)

Available on crate feature smoltcp only.

A smoltcp send call returned an error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

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.
