Error returned when a snapshot cannot be opened as a CSR graph.

Performance

perf: unspecified; errors are returned only from snapshot-bound paths.

Variants

MissingOffsets

The snapshot has no CSR offsets section for the requested edge width.

MissingTargets

The snapshot has no CSR targets section for the requested node width.

OffsetsVersion

The CSR offsets section was present but its version did not match.

Fields

kind: u32

Offsets section kind that was bound.

expected: u32

Section version the reader required.

actual: u32

Section version recorded in the snapshot.

TargetsVersion

The CSR targets section was present but its version did not match.

Fields

kind: u32

Targets section kind that was bound.

expected: u32

Section version the reader required.

actual: u32

Section version recorded in the snapshot.

OffsetsView(SectionViewError)

The CSR offsets section payload could not be borrowed as the selected little-endian index word slice.

TargetsView(SectionViewError)

The CSR targets section payload could not be borrowed as the selected little-endian index word slice.

OffsetsEmpty

The CSR offsets section is empty; CSR requires at least one entry for the n-plus-one layout.

NodeCountOverflow

The derived node count would not fit in the selected index type.

Fields

offsets_len: usize

Length of the offsets section.

Csr(CsrError<NodeIndex, EdgeIndex>)

CSR-shape validation failed on the borrowed sections.

Trait Implementations

impl<NodeIndex: Clone, EdgeIndex: Clone> Clone for CsrSnapshotError<NodeIndex, EdgeIndex>

fn clone(&self) -> CsrSnapshotError<NodeIndex, EdgeIndex>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<NodeIndex: Debug, EdgeIndex: Debug> Debug for CsrSnapshotError<NodeIndex, EdgeIndex>

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

Formats the value using the given formatter.

impl<NodeIndex, EdgeIndex> Display for CsrSnapshotError<NodeIndex, EdgeIndex>

where NodeIndex: Display, EdgeIndex: Display,

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

Formats the value using the given formatter.

impl<NodeIndex, EdgeIndex> Error for CsrSnapshotError<NodeIndex, EdgeIndex>

where NodeIndex: Debug + Display, EdgeIndex: Debug + Display,

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<NodeIndex, EdgeIndex> From<CsrError<NodeIndex, EdgeIndex>> for CsrSnapshotError<NodeIndex, EdgeIndex>

fn from(error: CsrError<NodeIndex, EdgeIndex>) -> Self

Converts to this type from the input type.

impl<NodeIndex: PartialEq, EdgeIndex: PartialEq> PartialEq for CsrSnapshotError<NodeIndex, EdgeIndex>

fn eq(&self, other: &CsrSnapshotError<NodeIndex, EdgeIndex>) -> 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.
