A malformed or unsupported topology.

Variants

UnsupportedVersion

The interchange version is not supported by this crate.

Fields

found: u16

Version found in the topology.

InvalidMetadata

Compressed-edge metadata contains invalid or transient bits.

Fields

metadata: u64

Rejected metadata word.

InvalidKeyLength

A value does not terminate at the unsigned key’s exact byte length.

Fields

found: usize

Number of key bytes represented by the path.

expected: usize

Required number of key bytes.

EmptyNode

A node has no live branches.

NodeCapacity

A node contains more branches than its recorded representation permits.

Fields

kind: NodeKind

Recorded node representation.

found: usize

Number of branches found.

DuplicateKey

Two branches in one node use the same radix byte.

Fields

key: u8

Duplicated radix byte.

InvalidSlot

A physical edge slot is invalid or duplicated.

Fields

kind: NodeKind

Recorded node representation.

slot: u16

Invalid physical slot.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
