Enum NodeInstantiationError 

pub enum NodeInstantiationError {
    MissingSchema(NodeKindKey),
    PortIdCountMismatch {
        expected: usize,
        actual: usize,
    },
}

Error returned when a node cannot be instantiated from schema.

Variants

MissingSchema(NodeKindKey)

The requested node kind is not registered.

PortIdCountMismatch

The caller supplied a different number of port ids than the schema declares.

Fields

expected: usize

actual: usize

Trait Implementations

impl Clone for NodeInstantiationError

fn clone(&self) -> NodeInstantiationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeInstantiationError

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

Formats the value using the given formatter.

impl Display for NodeInstantiationError

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

Formats the value using the given formatter.

impl Eq for NodeInstantiationError

impl Error for NodeInstantiationError

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<NodeInstantiationError> for CreateNodeError

fn from(source: NodeInstantiationError) -> Self

Converts to this type from the input type.

impl PartialEq for NodeInstantiationError

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