Enum CoordinationError 

#[non_exhaustive]
pub enum CoordinationError {
    Record(RecordError),
    Client(ClientError),
    Producer(ProducerError),
    Admin(AdminError),
    Fenced {
        role: Role,
    },
    NotHeld {
        role: Role,
        member: MemberId,
    },
    AcquireTimeout {
        role: Role,
    },
    InvalidConfig(String),
}

A fault that the coordination client reports.

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.

Record(RecordError)

A record of the coordination topic did not decode, or a name did not pass its constructor.

Client(ClientError)

The connection layer failed.

Producer(ProducerError)

The producer failed for a reason other than a fence.

Admin(AdminError)

The admin client failed.

Fenced

The broker fenced this member, so another member holds the role now.

This is the expected end of a leadership. The caller stops the work of the role at once. The epoch it held is superseded, so the cluster already rejects every write it makes.

Fields

role: Role

The role that this member no longer holds.

NotHeld

The caller asked a leadership handle to act after it resigned.

Fields

role: Role

The role that the handle named.

member: MemberId

The member that the handle named.

AcquireTimeout

The acquire call reached its deadline before this member won the role.

Another member held the role for the whole wait. A caller that must keep waiting calls acquire again.

Fields

role: Role

The role that this member competed for.

InvalidConfig(String)

A configuration value is outside the range that the client accepts.

Implementations

impl CoordinationError

pub fn is_fenced(&self) -> bool

Report whether the broker fenced this member.

A caller uses this to separate the loss of a role, which is an ordinary event, from a fault that a retry could clear.

Trait Implementations

impl Debug for CoordinationError

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

Formats the value using the given formatter.

impl Display for CoordinationError

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

Formats the value using the given formatter.

impl Error for CoordinationError

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.
