Enum PortRecvError 

pub enum PortRecvError {
    UnknownPort {
        port_id: PortId,
    },
    Disconnected {
        port_id: PortId,
    },
    Cancelled {
        port_id: PortId,
    },
}

Error returned when an input port cannot provide a packet.

Variants

UnknownPort

The node does not declare the requested input port.

Fields

port_id: PortId

Port requested by the caller.

Disconnected

All upstream senders for this input have disconnected.

Fields

port_id: PortId

Input port being received from.

Cancelled

The receive was cancelled before it could complete.

Fields

port_id: PortId

Input port being received from.

Trait Implementations

impl Clone for PortRecvError

fn clone(&self) -> PortRecvError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortRecvError

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

Formats the value using the given formatter.

impl Display for PortRecvError

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

Formats the value using the given formatter.

impl Error for PortRecvError

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<PortRecvError> for PureflowError

fn from(value: PortRecvError) -> Self

Converts to this type from the input type.

impl PartialEq for PortRecvError

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