    InvalidResponse(String),
    InvalidRow {
        kind: &'static str,
        index: usize,
        details: String,

    DuplicateExternalIdentity(ExternalId),
    MultipleGraphMetadataRows {

    },
    Graph(GraphError),
}

Failure to validate raw graph response bytes.

Variants

InvalidResponse(String)

The response is not the expected two-array result object.

InvalidRow

A projected row is missing or contains an invalid field.

Fields

kind: &'static str

node or edge.

index: usize

Zero-based row index.

details: String

Validation details.

IncompleteSelection

More rows existed than the explicit safety limit permits.

Fields

kind: &'static str

node or edge.

limit: usize

Configured maximum complete result size.

DuplicateExternalIdentity(ExternalId)

Two internal nodes map to the same external identity.

MultipleGraphMetadataRows

Graph metadata selection returned more than one row.

Fields

count: usize

Number of returned rows.

Graph(GraphError)

Graph construction found a topology invariant violation.

Trait Implementations

impl Debug for GraphLoadError

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

Formats the value using the given formatter.

impl Display for GraphLoadError

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

Formats the value using the given formatter.

impl Error for GraphLoadError

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<GraphError> for GraphLoadError

fn from(source: GraphError) -> Self

Converts to this type from the input type.
