Enum PeerError 

#[non_exhaustive]
pub enum PeerError {
    Bind(String),
    NoSession,
    SessionEnded,
    NotObserved {
        what: String,
    },
}

Everything that can go wrong driving the peer.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bind(String)

The loopback listener could not be bound.

NoSession

No client is connected, so there is nothing to send the directive to.

SessionEnded

The connection ended before the directive could be performed.

NotObserved

The record never satisfied the condition within OBSERVATION_BOUND.

Fields

what: String

What the caller was waiting for, in its own words.

Trait Implementations

impl Debug for PeerError

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

Formats the value using the given formatter.

impl Display for PeerError

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

Formats the value using the given formatter.

impl Error for PeerError

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>)
