Why a Link can’t run.

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.

OwnPort

The node’s own UDP port is 0.

Renewal

A foreign device’s time-to-live is 0, or its renewal interval isn’t above zero and below the time-to-live.

ResponseTimeout

A foreign device’s response timeout is zero.

BbmdPort

A foreign device’s BBMD has UDP port 0.

BbmdAddress

A foreign device’s BBMD is the unspecified address or a group address (Groups::contains), which no BBMD answers from.

BbmdIsSelf

A foreign device’s BBMD is the node itself.

Budget

The datagram budget is below MIN_BUDGET octets.

NotForeign

Node::retarget on a node that is not a foreign device.

MulticastMode

A multicast group as the subnet’s broadcast address (B/IP-M, Annex J.8) in Mode::Foreign: a foreign device broadcasts through its BBMD, never to a group.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ConfigError

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Eq for ConfigError

impl Error for ConfigError

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 PartialEq for ConfigError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
