Enum RetryTrigger 

#[non_exhaustive]
pub enum RetryTrigger {
    TransportError,
    Timeout,
    Status(u16),
    NonRetryable,
}

Conditions that trigger a retry

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.

TransportError

Transport-level errors (connection refused, DNS failure, reset, etc.)

Timeout

Request timeout

Status(u16)

Specific HTTP status code

NonRetryable

Error that is never retryable (e.g., DeadlineExceeded, ServiceClosed)

Trait Implementations

impl Clone for RetryTrigger

fn clone(&self) -> RetryTrigger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetryTrigger

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

Formats the value using the given formatter.

impl Hash for RetryTrigger

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for RetryTrigger

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
