Enum mpi::MpiError

pub enum MpiError {
    Spawn(Rank, Rank),
    StringNul(NulError),
}

Errors

RSMPI is currently configured with MPI_ERRORS_ARE_FATAL, but:

1. we intend to remove this restriction at some point

2. we need to be able to return parse errors and it seems better to make a stable error type than to propagate raw types like ``std::ffi::NulError` in our public interface.

Standard section(s)

9.3

Variants

Spawn(Rank, Rank)

Failed to spawn some processes

StringNul(NulError)

CString::new fails if a Rust string contains interior 0 bytes

Trait Implementations

impl Debug for MpiError

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

Formats the value using the given formatter.

impl Display for MpiError

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

Formats the value using the given formatter.

impl Error for MpiError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<NulError> for MpiError

fn from(source: NulError) -> Self

Converts to this type from the input type.
