Errors that can occur during port operations

Variants

NotFound(String)

Port not found

DirectionMismatch

Port direction mismatch (e.g., trying to connect output to output)

Fields

expected: PortDirection

Expected direction

got: PortDirection

Actual direction

TypeMismatch

Port type mismatch (e.g., trying to connect signal to control)

Fields

expected: PortType

Expected port type

got: PortType

Actual port type

AlreadyConnected(String)

Port already connected

MaxConnectionsReached(String)

Maximum connections reached

InvalidIndex(usize)

Invalid port index

Implementations

impl PortError

pub fn not_found(port: impl Display) -> Self

Create a new not found error

pub fn direction_mismatch(expected: PortDirection, got: PortDirection) -> Self

Create a new direction mismatch error

pub fn type_mismatch(expected: PortType, got: PortType) -> Self

Create a new type mismatch error

pub fn already_connected(port: impl Display) -> Self

Create a new already connected error

Trait Implementations

impl Clone for PortError

fn clone(&self) -> PortError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortError

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

Formats the value using the given formatter.

impl Display for PortError

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

Formats the value using the given formatter.

impl Eq for PortError

impl Error for PortError

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<PortError> for ProcessError

fn from(err: PortError) -> Self

Converts to this type from the input type.

impl PartialEq for PortError

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