Enum Error 

pub enum Error {
    Cluster {
        operation: String,
        message: String,
        code: Option<i32>,
        source: Option<Box<dyn Error + Send + Sync>>,
    },
    Transport {
        operation: String,
        message: String,
        source: Option<Box<dyn Error + Send + Sync>>,
    },
    Timeout {
        operation: String,
    },
    Conversion(String),
    Unsupported {
        transport: Transport,
        what: &'static str,
    },
}

A failure from either transport.

Variants

Cluster

The cluster refused the request.

code is the YTsaurus error code where one was reported. Both transports produce them from the same table, so a caller can match on them without knowing which wire it is on.

Fields

operation: String

message: String

code: Option<i32>

source: Option<Box<dyn Error + Send + Sync>>

Transport

The cluster could not be reached, or the connection failed mid-request.

Fields

operation: String

message: String

source: Option<Box<dyn Error + Send + Sync>>

Timeout

The request did not complete inside its deadline.

Fields

operation: String

Conversion(String)

A value or row could not be converted between this interface’s model and the transport’s.

Unsupported

The transport does not implement this, and says so rather than pretending.

Fields

transport: Transport

what: &'static str

Implementations

impl Error

pub fn code(&self) -> Option<i32>

The YTsaurus error code, if the cluster reported one.

pub fn is_retryable(&self) -> bool

Whether this is worth trying again.

Deliberately coarse: a transport failure or a timeout may succeed on a second attempt, and a refusal from the cluster generally will not. A caller that needs the real retry rules should use the transport’s own client, which has them.

pub fn cluster( operation: impl Into<String>, message: impl Into<String>, code: Option<i32>, ) -> Self

Builds a cluster refusal.

pub fn cluster_from( operation: impl Into<String>, code: Option<i32>, source: impl Error + Send + Sync + 'static, ) -> Self

Builds a cluster refusal that keeps the transport’s own error.

pub fn transport_from( operation: impl Into<String>, source: impl Error + Send + Sync + 'static, ) -> Self

Builds a transport failure that keeps the transport’s own error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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>)
