Enum Error 

pub enum Error {
    Io(Error),
    Timeout(Duration),
    Handshake(String),
    InvalidGroup(String),
    PeerClosed(usize),
    Desync {
        rank: usize,
        expected: Tag,
        received: Tag,
    },
    LengthMismatch {
        rank: usize,
        expected: usize,
        found: usize,
    },
}

A collective failure; the ranks can no longer agree.

Variants

Io(Error)

A socket operation failed.

Timeout(Duration)

The peers did not all connect in time.

Handshake(String)

A connection did not introduce itself as a rank of this mesh.

InvalidGroup(String)

The ranks do not form a valid group.

PeerClosed(usize)

A peer’s connection closed.

Desync

A peer sent a frame of another collective.

Fields

rank: usize

The peer.

expected: Tag

The collective this rank is in.

received: Tag

The collective the peer sent.

LengthMismatch

The members passed reductions of different lengths.

Fields

rank: usize

The peer.

expected: usize

Values this rank passed.

found: usize

Values the peer passed.

Trait Implementations

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 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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
