Enum polkadot_overseer::OverseerError

pub enum OverseerError {
    NotifyCancellation(Canceled),
    QueueError,
    TaskSpawn(&'static str),
    Infallible(Infallible),
    Context(String),
    SubsystemStalled(&'static str, &'static str, &'static str),

    },
}

An error type that describes faults that may happen

These are:

• Channels being closed
• Subsystems dying when they are not expected to
• Subsystems not dying when they are told to die
• etc.

Variants

NotifyCancellation(Canceled)

QueueError

TaskSpawn(&'static str)

Infallible(Infallible)

Context(String)

SubsystemStalled(&'static str, &'static str, &'static str)

FromOrigin

Per origin (or subsystem) annotations to wrap an error.

Fields

origin: &'static str

An additional annotation tag for the origin of source.

source: Box<dyn Error + Send + Sync>

The wrapped error. Marked as source for tracking the error chain.

Trait Implementations

impl Debug for OrchestraError

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

Formats the value using the given formatter.

impl Display for OrchestraError

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

Formats the value using the given formatter.

impl Error for OrchestraError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
