}

Typed graph node-block encode/decode failure.

Variants

Control

A controlled encode/decode operation was interrupted.

Truncated

The region is shorter than its bounded fixed trailer or block geometry.

Fields

minimum: usize

Minimum bytes required by the declared format.

actual: usize

Bytes supplied by the caller.

InvalidHeader(String)

Fixed magic, version, flags, lengths, or reserved trailer bytes are invalid.

Layout(String)

Layout geometry cannot describe a bounded fixed-stride region.

NodeIdOutOfRange

A node id is outside the dense row-id range.

Fields

node_id: u32

Requested graph node / segment row id.

node_count: u32

Number of nodes present in the region.

InvalidNode

One node’s production input violates the persisted contract.

Fields

node_id: u32

Dense graph node / segment row id.

detail: String

Contract violation.

ArithmeticOverflow

Checked offset or length arithmetic overflowed.

Trait Implementations

impl Clone for GraphNodeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphNodeError

impl Eq for GraphNodeError

impl Error for GraphNodeError

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
