Enum OrderingError 

pub enum OrderingError {
    MalformedInput,
    NonSymmetric,
    IndexOverflow,
    DisconnectedGraph,
    Internal(&'static str),
}

Shared error shape for the ordering-crate contract.

Crate-specific failure modes are carried via OrderingError::Internal rather than a wrapped crate-specific enum, to avoid an error-type dependency tree between the sibling crates.

Variants

MalformedInput

Input failed CscPattern::new validation (wrong lengths, out-of-range row indices, etc.).

NonSymmetric

Input pattern was not structurally symmetric. Debug-only detection; release builds trust the caller.

IndexOverflow

Index overflow in the crate’s internal workspace (for example, i32 overflow on a very large matrix).

DisconnectedGraph

Graph is disconnected and the crate does not handle disconnected components in its current form.

Internal(&'static str)

Crate-specific failure with a short static message. Keep short — this is a status channel, not a rich diagnostic.

Trait Implementations

impl Clone for OrderingError

fn clone(&self) -> OrderingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderingError

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

Formats the value using the given formatter.

impl Display for OrderingError

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

Formats the value using the given formatter.

impl Eq for OrderingError

impl Error for OrderingError

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 OrderingError

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