Enum RefusalKind 

Source 
pub enum RefusalKind {
    VersionUnsupported,
    VersionBlocked,
    ServiceUnknown,
    RateLimited,
    ShuttingDown,
    Other(ErrorCode),
}
Expand description

Stable, matchable classification of a broker HelloReply::Refused code.

This is the consumer-facing decision surface for the broker’s refusal codes: the wire carries an ErrorCode i32, but a future broker may add codes a consumer’s build predates. Matching on RefusalKind keeps consumer retry logic exhaustive and forward-compatible — any unrecognized code lands in RefusalKind::Other rather than silently mismatching.

Variants§

§

VersionUnsupported

The requested version is below the backend’s min_version or otherwise not offered. Caller should upgrade/downgrade, not blindly retry.

§

VersionBlocked

The requested version is explicitly blocked (e.g. yanked). Do not retry with the same version.

§

ServiceUnknown

The service name is unknown to this broker. A configuration error; retrying will not help.

§

RateLimited

The broker is rate-limiting this peer. Honour retry_after_ms.

§

ShuttingDown

The broker is shutting down. Retry against a fresh broker.

§

Other(ErrorCode)

Any other refusal code (peer rejected, internal, fd pressure, spawn failure, unspecified, or a code newer than this build understands).
