Enum AdminError 

pub enum AdminError {
    Connect {
        tried: usize,
        source: Option<Box<Self>>,
    },
    InvalidConfig(String),
    InvalidArgument(String),
    Broker {
        api: &'static str,
        code: i16,
        name: &'static str,
        message: Option<String>,
    },
    Transport(ClientError),
    Protocol(String),
}

Variants

Connect

No bootstrap address gave a usable connection. source holds the error from the last address tried, and is None only when the list was empty. Match it to tell an unreachable or silent broker ([ClientError::Connect] or [ClientError::Timeout]) from a TLS or SASL failure with no verdict from the peer ([ClientError::Tls] or [ClientError::Sasl]).

A rejected authentication does not give this error. The client stops at the first address that rejects it and returns AdminError::Transport(ClientError::Authentication { .. }), as Kafka’s AdminMetadataManager makes an AuthenticationException fatal.

Fields

tried: usize

source: Option<Box<Self>>

InvalidConfig(String)

A setting of AdminClientConfig is invalid, as Kafka raises a ConfigException when it builds the admin client.

InvalidArgument(String)

An argument of a call is invalid, as Kafka’s admin types throw an IllegalArgumentException before anything is sent.

Broker

Fields

api: &'static str

code: i16

name: &'static str

message: Option<String>

Transport(ClientError)

Protocol(String)

Implementations

impl AdminError

pub const fn is_authentication_failure(&self) -> bool

Whether a peer rejected authentication. Kafka’s admin client fails the call with the AuthenticationException and does not retry (KafkaAdminClient handleResponses, AdminMetadataManager.updateFailed).

Trait Implementations

impl Debug for AdminError

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

Formats the value using the given formatter.

impl Display for AdminError

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

Formats the value using the given formatter.

impl Error for AdminError

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.

impl From<ClientError> for AdminError

fn from(source: ClientError) -> Self

Converts to this type from the input type.
