Enum FailureClass 

#[non_exhaustive]
pub enum FailureClass {
    Transient,
    Permanent,
    InfraCrash,
    Timeout,
    Cancelled,
}

Failure classification — determines retry disposition on the Lua side. Mirrors the Lua-side classification codes.

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.

Transient

Retryable transient error.

Permanent

Permanent error — no retries.

InfraCrash

Crash / process death inferred from lease expiry.

Timeout

Timeout at the attempt or operation level.

Cancelled

Cooperative cancellation by operator or cancel_flow.

Trait Implementations

impl Clone for FailureClass

fn clone(&self) -> FailureClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailureClass

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

Formats the value using the given formatter.

impl Hash for FailureClass

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FailureClass

fn eq(&self, other: &FailureClass) -> 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.
