Struct PlacementError 

pub struct PlacementError { /* private fields */ }

Error converged across every rank in a placement collective.

Implementations

impl PlacementError

pub const fn kind(&self) -> PlacementErrorKind

Returns the stable failure category.

pub const fn rank(&self) -> Option<i32>

Returns the lowest rank that reported the converged failure.

pub fn message(&self) -> &str

Returns the bounded diagnostic message.

Trait Implementations

impl Clone for PlacementError

fn clone(&self) -> PlacementError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlacementError

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

Formats the value using the given formatter.

impl Display for PlacementError

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

Formats the value using the given formatter.

impl Eq for PlacementError

impl Error for PlacementError

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 PlacementError

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