Error generated when linking ports.

Variants

AlreadyLinked

Fields

port: PortIndex

The port is already linked.

UnknownPort

Fields

port: PortIndex

The port does not exist.

UnknownOffset

Fields

node: NodeIndex

offset: PortOffset

The port offset is invalid.

IncompatibleDirections

Fields

port_a: PortIndex

port_b: PortIndex

dir: Direction

The ports have the same direction so they cannot be linked.

Trait Implementations

impl Clone for LinkError

fn clone(&self) -> LinkError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LinkError

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

Formats the value using the given formatter.

impl Display for LinkError

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

Formats the value using the given formatter.

impl Error for LinkError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<LinkError> for LinkError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
