        index: u32,
    },

}

A graph rejected an operation or relationship outside the restricted model.

Variants

InvalidSourceRange

A caller supplied a source range whose end precedes its start.

SourceRangeCountMismatch

Sidecar source ranges no longer align with the normalized graph.

GraphTooLarge

The graph cannot represent more nodes than its local references allow.

NodeOutOfRange

An edge referenced no operation in this graph.

Fields

index: u32

Graph-local node position that no node occupies.

SelfEdge

An operation cannot depend on itself.

Fields

index: u32

Graph-local node position used as both endpoints.

DuplicateEdge

The same edge was supplied more than once.

ResourceKindMissing

An acquire or release omitted the category required to pair it safely.

Fields

index: usize

Graph-local node position of the incomplete resource operation.

UnexpectedResourceKind

A non-resource operation attempted to carry a resource category.

Fields

index: usize

Graph-local node position carrying unsupported resource metadata.

InvalidResourceLifetime

A resource edge must pair matching acquire and release operations.

Trait Implementations

impl Debug for SemanticGraphError

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

Formats the value using the given formatter.

impl Display for SemanticGraphError

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

Formats the value using the given formatter.

impl Eq for SemanticGraphError

impl Error for SemanticGraphError

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 PartialEq for SemanticGraphError

fn eq(&self, other: &SemanticGraphError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
