Enum RetryError 

pub enum RetryError {
    Canceled,
    OperationTimeout {
        timeout_ms: u64,
    },
    ElapsedBudgetExceeded {
        attempt: u32,
        max_attempts: u32,
        last_error: Option<String>,
    },
    InvalidConfiguration {
        message: String,
    },
}

A failure synthesized by retry machinery.

This type describes the retry control path only. It does not indicate whether an operation was transmitted or applied.

Variants

Canceled

The cancellation token was set.

OperationTimeout

A single operation attempt exceeded its configured timeout.

Fields

timeout_ms: u64

Configured timeout for each attempt in milliseconds.

ElapsedBudgetExceeded

The total elapsed-time budget was exhausted.

Fields

attempt: u32

One-based attempt position when the budget was exhausted.

max_attempts: u32

Maximum number of attempts allowed by the retry configuration.

last_error: Option<String>

Last operation error when budget exhaustion followed a failed attempt.

InvalidConfiguration

The retry configuration could not create a backoff state.

Fields

message: String

Configuration validation error.

Trait Implementations

impl Clone for RetryError

fn clone(&self) -> RetryError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RetryError

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

Formats the value using the given formatter.

impl Eq for RetryError

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.

impl PartialEq for RetryError

fn eq(&self, other: &RetryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
