Struct TopologyError 

pub struct TopologyError {
    pub kind: TopologyErrorKind,
    pub message: String,
    pub recovery: TopologyRecoveryHint,
}

Machine-readable topology failure with an agent-facing recovery hint.

When an agent receives this error, the recovery field holds a stable enumeration value the agent can match on to choose its next action without parsing free-text messages.

Fields

kind: TopologyErrorKind

message: String

recovery: TopologyRecoveryHint

Stable hint telling an agent what recovery action to take next.

impl Error for TopologyError

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
