Enum Recoverability 

pub enum Recoverability {
    Transient,
    Permanent,
    Unknown,
}

Classification of error recoverability for retry logic.

This enum helps the retry combinator and error handling code decide how to handle failures.

Variants

Transient

Temporary failure that may succeed on retry.

Permanent

Permanent failure that will not succeed on retry.

Unknown

Recoverability depends on context and cannot be determined from the error kind alone.

Implementations

impl Recoverability

pub const fn should_retry(&self) -> bool

Returns true if this error is safe to retry.

pub const fn is_permanent(&self) -> bool

Returns true if this error should never be retried.

Trait Implementations

impl Clone for Recoverability

fn clone(&self) -> Recoverability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Recoverability

impl Debug for Recoverability

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

Formats the value using the given formatter.

impl Eq for Recoverability

impl Hash for Recoverability

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 Recoverability

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