Errors returned by the multicast sender core.

Variants

InvalidDestinationPort

The configured destination port is invalid.

InvalidMulticastGroup

The configured group address is not a valid multicast IP address.

InvalidSourcePort

The configured source port is invalid.

InvalidSourceAddress

The configured source IP address is invalid.

InvalidInterfaceAddress

The configured multicast interface selector is invalid.

InvalidIpv6InterfaceIndex

The configured IPv6 interface index is invalid.

InvalidRawBindAddress

The configured raw bind address is invalid.

SourceAddressFamilyMismatch

The configured source address does not match the group address family.

OutgoingInterfaceFamilyMismatch

The configured outgoing interface does not match the group address family.

RawBindAddressFamilyMismatch

The configured raw bind address does not match the expected datagram family.

Ipv6SourceInterfaceMismatch

The configured IPv6 source address and outgoing interface disagree about which interface should be used.

Fields

source_addr: IpAddr

source_interface_index: u32

outgoing_interface_index: u32

Ipv6ScopedMulticastRequiresInterface

A scoped IPv6 multicast destination needs a concrete interface index.

InterfaceDiscoveryFailed(String)

Resolving a local IPv6 address to its interface index failed.

DuplicatePublication

A publication with the same configuration already exists.

PublicationNotFound

No publication with the requested ID exists.

SocketCreateFailed(Error)

Creating the UDP socket failed.

SocketOptionFailed(Error)

Setting a socket option failed.

SocketBindFailed(Error)

Binding the UDP socket failed.

SocketConnectFailed(Error)

Connecting the UDP socket failed.

SocketLocalAddrFailed(Error)

Reading the local address from a socket failed.

ExistingSocketAddressFamilyMismatch

The provided existing socket does not match the configured IP family.

ExistingSocketPortMismatch

The provided existing socket is bound to a different UDP port than requested.

Fields

expected: u16

actual: u16

ExistingSocketAddressMismatch

The provided existing socket is bound to a different local IP address than requested.

Fields

expected: IpAddr

actual: IpAddr

SendFailed(Error)

Sending a packet failed.

RawPacketTransmitUnsupported(String)

Raw multicast packet transmit is not supported on the current platform or configuration.

RawSocketCreateFailed(Error)

Creating the raw transmit socket failed.

RawSocketBindFailed(Error)

Binding the raw transmit socket failed.

RawSendFailed(Error)

Sending a raw IP datagram failed.

InvalidRawIpDatagram

The supplied raw datagram bytes are not a valid complete IPv4 or IPv6 datagram.

InvalidRawMulticastDestination

The supplied raw datagram does not target a multicast destination.

RawDatagramSourceMismatch

The supplied raw datagram source conflicts with the configured bind address.

Fields

datagram_source: IpAddr

configured_bind_addr: IpAddr

RawInterfaceRequired

Raw packet transmit needs an explicit outgoing interface selection.

RawUnsupportedLinkType(String)

Raw packet transmit is not implemented for the selected link type.

Trait Implementations

impl Debug for MctxError

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

Formats the value using the given formatter.

impl Display for MctxError

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

Formats the value using the given formatter.

impl Error for MctxError

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.
