Enum ErrorClass 

#[non_exhaustive]
pub enum ErrorClass {
    Interrupted,
    VariantChange,
    Other,
}

Single-discriminant classification of a DecodeError.

Walking the source chain via separate per-class boolean predicates in sequence forces the chain to be traversed twice on the failure path. DecodeError::classify runs the walk once and returns this tag so callers can match instead of cascading boolean predicates.

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.

Interrupted

Interrupted by seek / cooperative pending — caller should retry.

VariantChange

Cross-variant boundary — caller must recreate the decoder.

Other

Anything else — caller surfaces as terminal failure.

Trait Implementations

impl Clone for ErrorClass

fn clone(&self) -> ErrorClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorClass

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

Formats the value using the given formatter.

impl PartialEq for ErrorClass

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