Enum SnapshotError 

pub enum SnapshotError {
    BusNotDrained {
        queued: usize,
        dropped: usize,
    },
}

Failures Node::snapshot() returns instead of panicking.

Variants

BusNotDrained

The in-Node typed bus still carries un-drained events at the moment snapshot() is invoked. A restore would either silently drop them or re-fire stale infra events — neither preserves Node fidelity. Callers drive Node::poll until the bus is empty before retrying.

Fields

queued: usize

Events still queued at snapshot time.

dropped: usize

FIFO-dropped events accumulated since the last drain.

Trait Implementations

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl Display for SnapshotError

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

Formats the value using the given formatter.

impl Error for SnapshotError

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.
