Variants

InvalidDestinationPort

The configured destination port is invalid.

InvalidMulticastGroup

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

InvalidSourceAddress

The configured SSM source address is invalid.

InvalidIpv6SsmGroup

The configured IPv6 SSM group is not in the IPv6 SSM range.

SourceAddressFamilyMismatch

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

InterfaceAddressFamilyMismatch

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

InvalidInterfaceIndex

The configured interface index is invalid.

InterfaceIndexRequiresIpv6

The configured interface index is only valid for IPv6 subscriptions.

DuplicateSubscription

A subscription with the same configuration already exists.

SubscriptionNotFound

No subscription with the requested ID exists.

SubscriptionNotJoined

The subscription is not currently joined to its multicast group.

SubscriptionAlreadyJoined

The subscription is already joined to its multicast group.

SocketCreateFailed(Error)

Creating the UDP socket failed.

SocketOptionFailed(Error)

Setting a socket option failed.

SocketBindFailed(Error)

Binding the UDP socket failed.

RawSocketCreateFailed(Error)

Creating the raw receive socket failed.

RawSocketBindFailed(Error)

Binding the raw receive socket failed.

RawPacketReceiveUnsupported(String)

Raw multicast receive is not supported on this platform in this build.

Ipv6NotYetImplemented

The requested IPv6 functionality is not implemented yet.

SocketLocalAddrFailed(Error)

Reading the local address of an existing socket failed.

SocketIoctlFailed(Error)

Looking up a socket extension function failed.

ExistingSocketAddressFamilyMismatch

The provided existing socket family does not match the subscription configuration.

ExistingSocketPortMismatch

Fields

expected: u16

actual: u16

MulticastJoinFailed(Error)

Joining a multicast group failed.

MulticastLeaveFailed(Error)

Leaving a multicast group failed.

SourceSpecificMulticastUnsupported

Source-specific multicast is not supported on this platform.

Ipv6SourceSpecificMulticastRequiresInterface

IPv6 source-specific multicast requires explicit interface selection.

Ipv6SourceSpecificMulticastNotYetImplemented

IPv6 source-specific multicast has not been wired into the receiver yet.

InterfaceProbeBindFailed(Error)

Binding the interface probe socket failed.

InterfaceProbeConnectFailed(Error)

Connecting the interface probe socket failed.

InterfaceProbeLocalAddrFailed(Error)

Trait Implementations

impl Debug for McrxError

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

Formats the value using the given formatter.

impl Display for McrxError

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

Formats the value using the given formatter.

impl Error for McrxError

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.
