Enum metis::NewGraphError

#[non_exhaustive]
pub enum NewGraphError {
    NoConstraints,
    NoParts,
    TooLarge,
    InvalidGraph(InvalidGraphError),
}

Error type returned by Graph::new.

Unlike Error, this error originates from the Rust bindings.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoConstraints

ncon must be greater than 1.

NoParts

nparts must be greater than 1.

TooLarge

Graph is too large. One of the array’s length doesn’t fit into Idx.

InvalidGraph(InvalidGraphError)

The input arrays are malformed and cannot be safely passed to METIS.

Note that these bindings do not check for all the invariants. Some might be raised during Graph::part_recursive and Graph::part_kway as Error::Input.

Trait Implementations

impl Debug for NewGraphError

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

Formats the value using the given formatter.

impl Display for NewGraphError

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

Formats the value using the given formatter.

impl Error for NewGraphError

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<NewGraphError> for Error

fn from(_: NewGraphError) -> Self

Converts to this type from the input type.
