Module khive_error 

Structured cross-crate error model for khive.

Ported from khive-internal’s foundation/types/src/error/.

Design

• KhiveError — unified error struct with kind + code + message + details
• ErrorKind — semantic severity / HTTP-mapping bucket
• ErrorCode — domain-scoped numeric code (ErrorDomain::Db, 1)
• Details — bounded key/value metadata (max 8 pairs)
• RetryHint — whether the caller should retry

All types are #![no_std] compatible. Serde impls are feature-gated behind the serde flag (existing crate pattern).

Structs

Details

Bounded key/value metadata attached to a KhiveError (max 8 pairs).

ErrorCode

Domain-scoped numeric error code.

KhiveError

Unified error type for the khive runtime.

Enums

ErrorDomain

Domain that owns the error code namespace.

ErrorKind

Semantic error category — maps to HTTP status codes.

RetryHint

Guidance to callers on whether retrying the operation makes sense.
