Enum BulkheadServiceError 

pub enum BulkheadServiceError<E> {
    Bulkhead(BulkheadError),
    Inner(E),
}

Service-level error that wraps inner service errors.

This error type is returned by the Bulkhead service and allows services with any error type to be wrapped without requiring From<BulkheadError> implementations.

Examples

use tower_resilience_bulkhead::BulkheadServiceError;

// Match on the error to determine the cause
fn handle_error<E: std::fmt::Debug>(err: BulkheadServiceError<E>) {
    match err {
        BulkheadServiceError::Bulkhead(e) => {
            println!("Bulkhead error: {}", e);
        }
        BulkheadServiceError::Inner(e) => {
            println!("Inner service error: {:?}", e);
        }
    }
}

Variants

Bulkhead(BulkheadError)

Bulkhead-specific error (full or timeout).

Inner(E)

Error from the inner service.

Implementations

impl<E> BulkheadServiceError<E>

pub fn is_bulkhead(&self) -> bool

Returns true if this is a bulkhead-specific error.

pub fn is_inner(&self) -> bool

Returns true if this is an inner service error.

pub fn into_inner(self) -> Option<E>

Converts this error into the inner error, if any.

pub fn bulkhead_error(&self) -> Option<&BulkheadError>

Returns a reference to the bulkhead error, if any.

Trait Implementations

impl<E: Debug> Debug for BulkheadServiceError<E>

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
