Enum RetryError 

pub enum RetryError {
    BudgetExhausted {
        attempts: u32,
    },
    NonRetryableError(String),
    MaxDelayExceeded,
}

Errors returned when the retry machinery refuses to issue another attempt.

Variants

BudgetExhausted

No more attempts remain (either the count or time budget was exceeded).

Fields

attempts: u32

Number of attempts that were made.

NonRetryableError(String)

The error is not retryable (e.g. a 4xx client error).

MaxDelayExceeded

The computed delay would exceed the remaining time budget.

Trait Implementations

impl Debug for RetryError

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

Formats the value using the given formatter.

impl Display for RetryError

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

Formats the value using the given formatter.

impl Error for RetryError

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.
