Enum GraphConstructionError

#[non_exhaustive]
pub enum GraphConstructionError {
    MismatchedGraphs,
    NodeHasMultipleOutputs {
        op: String,
        signal_type: String,
    },
    FilesystemError(Error),
}

An error that occurred while constructing a graph.

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.

MismatchedGraphs

Attempted to connect nodes from different graphs.

NodeHasMultipleOutputs

Attempted to perform an invalid operation on a node with multiple outputs.

Fields

op: String

The operation that was attempted.

signal_type: String

The type of the node.

FilesystemError(Error)

Filesystem error.

Trait Implementations

impl Debug for GraphConstructionError

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

Formats the value using the given formatter.

impl Display for GraphConstructionError

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

Formats the value using the given formatter.

impl Error for GraphConstructionError

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<Error> for GraphConstructionError

fn from(source: Error) -> Self

Converts to this type from the input type.
