Enum ClientGroupError 

pub enum ClientGroupError {
    Empty,
    BlockingDeviceHandle,
    MixedRuntimes,
    NoDeviceTransport {
        runtime: &'static str,
    },
    NotAscending {
        devices: Vec<DeviceId>,
    },
}

Why clients cannot form a ClientGroup.

Variants

Empty

There are no clients.

BlockingDeviceHandle

The device handle blocks the caller, which collectives cannot run on.

MixedRuntimes

The clients run different runtimes, which share no transport.

NoDeviceTransport

The runtime has no transport between its devices.

Fields

runtime: &'static str

The runtime’s name.

NotAscending

The devices are not in strictly ascending order, so a member would not be its rank, or a device would hold two ranks.

Fields

devices: Vec<DeviceId>

The devices, in the order given.

Trait Implementations

impl Clone for ClientGroupError

fn clone(&self) -> ClientGroupError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientGroupError

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

Formats the value using the given formatter.

impl Display for ClientGroupError

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

Formats the value using the given formatter.

impl Eq for ClientGroupError

impl Error for ClientGroupError

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 ClientGroupError

fn eq(&self, other: &ClientGroupError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
