Enum SendToError 

pub enum SendToError {
    NotWriteable,
    CreateSock(IpSockCreationError),
    Send(IpSockSendError),
    Zone(ZonedAddressError),
    RemotePortUnset,
    RemoteUnexpectedlyMapped,
    RemoteUnexpectedlyNonMapped,
    SendBufferFull,
    InvalidLength,
}

An error encountered while sending a UDP packet to an alternate address.

Variants

NotWriteable

The socket is not writeable.

CreateSock(IpSockCreationError)

An error was encountered while trying to create a temporary IP socket to use for the send operation.

Send(IpSockSendError)

An error was encountered while trying to send via the temporary IP socket.

Zone(ZonedAddressError)

There was a problem with the remote address relating to its zone.

RemotePortUnset

Disallow sending packets with a remote port of 0. See UdpRemotePort::Unset for the rationale.

RemoteUnexpectedlyMapped

The remote address is mapped (i.e. an ipv4-mapped-ipv6 address), but the socket is not dual-stack enabled.

RemoteUnexpectedlyNonMapped

The remote address is non-mapped (i.e not an ipv4-mapped-ipv6 address), but the socket is dual stack enabled and bound to a mapped address.

SendBufferFull

The socket’s send buffer is full.

InvalidLength

Invalid message length.

Trait Implementations

impl Clone for SendToError

fn clone(&self) -> SendToError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SendToError

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

Formats the value using the given formatter.

impl Display for SendToError

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

Formats the value using the given formatter.

impl Error for SendToError

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<IpSockCreationError> for SendToError

fn from(source: IpSockCreationError) -> Self

Converts to this type from the input type.

impl From<IpSockSendError> for SendToError

fn from(source: IpSockSendError) -> Self

Converts to this type from the input type.

impl From<ZonedAddressError> for SendToError

fn from(source: ZonedAddressError) -> Self

Converts to this type from the input type.

impl PartialEq for SendToError

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