Enum RetryPermitError 

pub enum RetryPermitError {
    TooEarly,
    MonotonicRollback,
    ElapsedBudgetExhausted,
}

Why a one-use retry permit did not authorize execution.

Variants

TooEarly

The caller observed a time before the authorized delay completed.

MonotonicRollback

The caller observation moved backward relative to controller state.

ElapsedBudgetExhausted

The hard elapsed budget expired before execution.

impl Eq for RetryPermitError

impl Error for RetryPermitError

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
