Enum OrleansError 

#[non_exhaustive]
pub enum OrleansError {
    Transport(Error),
    Status(Status),
    Serialization(String),
    Bridge {
        code: String,
        message: String,
        detail: Option<String>,
        retryable: bool,
    },
    Timeout,
    InvalidConfig(String),
}

Errors returned by crate::OrleansClient and grain calls.

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.

Transport(Error)

The gRPC channel could not be established.

Status(Status)

A transport-level gRPC status that did not carry structured bridge error metadata.

Serialization(String)

A request or response payload could not be (de)serialized on the client side.

Bridge

A structured, Orleans-level error reported by the bridge. The code field is one of codes.

Fields

code: String

Stable error code; see codes.

message: String

Human-readable description.

detail: Option<String>

Optional additional detail (only populated in dev mode).

retryable: bool

Whether the caller may safely retry the request.

Timeout

The call exceeded its client-side deadline.

InvalidConfig(String)

The client was misconfigured.

Implementations

impl OrleansError

pub fn is_retryable(&self) -> bool

Whether the failed call is safe to retry. Retryable bridge errors, Unavailable, and bare timeouts are considered transient.

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

The stable error code, if this is a structured bridge error.

Trait Implementations

impl Debug for OrleansError

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

Formats the value using the given formatter.

impl Display for OrleansError

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

Formats the value using the given formatter.

impl Error for OrleansError

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<Error> for OrleansError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Status> for OrleansError

fn from(source: Status) -> Self

Converts to this type from the input type.
