Enum WarningCode 

pub enum WarningCode {
    AxonW002,
}

Closed catalog of runtime warning codes that can surface on the production SSE wire.

As of 33.x.g there is exactly one wire-body code: AxonW002. W001 was reserved by Fase 31.e but ships as the X-Axon-Stream-Available HTTP header (header-level diagnostic), NOT as a wire-body warning. Future codes (W003+) require an explicit founder sign-off and a closed-catalog drift gate update — adding a variant here is not silent.

Variants

AxonW002

axon-W002 streaming-not-supported — emitted when the adopter’s flow declared output: Stream<T> but the production async streaming path could not activate, and the runtime fell back to the legacy synchronous-burst delivery. The accompanying FallbackMode tag captures the specific reason (flow shape unsupported, backend unknown, etc.).

Wire surface: axon.complete.warnings[*] (D4-compatible optional array, elided when empty). Audit surface: replay.runtime_warnings[*] on the AxonendpointReplayEntry.

Implementations

impl WarningCode

pub fn slug(&self) -> &'static str

Stable wire slug. Closed catalog — adding a variant above requires updating this match (compiler enforces exhaustiveness).

pub fn message(&self) -> &'static str

Human-readable summary surfaced on the wire alongside the slug. The accompanying FallbackMode provides the machine-readable detail.
