Enum ErrorCategory 

#[non_exhaustive]
pub enum ErrorCategory {
    Network,
    Timeout,
    Session,
    RoutePath,
    CipProtocol,
    BatchEmbeddedService,
    KnownControllerLimitation,
    DataType,
    NotFound,
    Unknown,
}

Stable error classification used by diagnostics and retry decisions.

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.

Network

Socket or other network I/O failure.

Timeout

Request deadline exceeded.

Session

EtherNet/IP session or connection failure.

RoutePath

Invalid or unreachable CIP route.

CipProtocol

General CIP protocol rejection.

BatchEmbeddedService

Failure reported by an embedded batch service.

KnownControllerLimitation

Recognized controller/firmware restriction.

DataType

Value type or encoding mismatch.

NotFound

Requested tag or path was not found.

Unknown

Error did not match a stable category.
