Error returned when a snapshot cannot be opened as a bipartite-CSR hypergraph view.

Performance

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

Variants

MissingSection

The snapshot is missing one of the eight required sections.

Fields

section: BcsrSection

Which section was missing.

kind: u32

The kind constant the lookup used.

VersionMismatch

A required section was present but its version did not match.

Fields

section: BcsrSection

Which section had the wrong version.

kind: u32

The kind constant the lookup used.

expected: u32

Version the reader required.

actual: u32

Version recorded in the snapshot.

SectionView

A required section payload could not be borrowed as [U32<LE>].

Fields

section: BcsrSection

Which section failed the typed-slice cast.

error: SectionViewError

The underlying snapshot error.

OffsetsEmpty

One of the offset sections was empty; bipartite-CSR requires at least one entry for the n-plus-one layout.

Fields

section: BcsrSection

Which offset section was empty.

CountOverflow

A derived count would not fit in u32.

Fields

section: BcsrSection

Which section’s length triggered the overflow.

offsets_len: usize

Length of the offsets section.

Bcsr(BcsrError)

Bipartite-CSR layout-shape error surfaced through the borrowed sections.

Trait Implementations

impl Clone for BcsrSnapshotError

fn clone(&self) -> BcsrSnapshotError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BcsrSnapshotError

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

Formats the value using the given formatter.

impl Display for BcsrSnapshotError

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

Formats the value using the given formatter.

impl Eq for BcsrSnapshotError

impl Error for BcsrSnapshotError

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<BcsrError> for BcsrSnapshotError

fn from(error: BcsrError) -> Self

Converts to this type from the input type.

impl PartialEq for BcsrSnapshotError

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