Enum HandlerErrorKind 

pub enum HandlerErrorKind {
    Callee,
    Caller,
    Infrastructure,
    NetworkPartition,
    LeaseExpired,
    HandlerUnavailable,
}

The kind discriminant for a HandlerError. Lets callers match on a specific failure mode without losing the message/cause chain.

Variants

Callee

CT-1 — the handler implementation is broken. Always a bug.

Caller

CT-2 — the Axon program made an invalid request.

Infrastructure

CT-3 — the physical world cannot answer.

NetworkPartition

Subtype of CT-3 — D4 partition = ⊥ void, NEVER doubt.

LeaseExpired

Subtype of CT-2 — D2 τ expired = Anchor Breach.

HandlerUnavailable

Subtype of CT-3 — backing SDK/binary missing.

Trait Implementations

impl Clone for HandlerErrorKind

fn clone(&self) -> HandlerErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HandlerErrorKind

impl Debug for HandlerErrorKind

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

Formats the value using the given formatter.

impl Eq for HandlerErrorKind

impl PartialEq for HandlerErrorKind

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