Enum BridgeBackend 

pub enum BridgeBackend {
    Embedded,
    Kafka {
        endpoint: String,
    },
    Nats {
        endpoint: String,
    },
}

Typed bridge backend selection, resolved from the flat TOML fields.

The TOML wire format deliberately keeps the shipped flat keys (bridge_backend = "kafka" + bridge_endpoint = …): this is a public tool with configs in the field, and a config_version bump that strands them is a hazard. Everything downstream of parsing works with these enums instead — each variant carries its required companions, so “kafka without an endpoint” is unrepresentable once resolved. The per-selector accessors on HarnessConfig (HarnessConfig::bridge and friends) are the SINGLE site that owns the legal-value vocabulary and the required-companion rules; validate() and the daemon’s backend factories both delegate to them (previously the four selectors were Strings whose legal values were enumerated twice, with companion rules spread across four more sites).

Variants

Embedded

Embedded broker persisting under bridge_data_dir.

Kafka

Kafka/Redpanda; endpoint is the host:port[,host:port] bootstrap list (not a URL — no scheme check applies).

Fields

endpoint: String

Bootstrap list, host:port[,host:port].

Nats

NATS JetStream; endpoint is a nats:// or tls:// URL.

Fields

endpoint: String

nats:// or tls:// URL.

Trait Implementations

impl Clone for BridgeBackend

fn clone(&self) -> BridgeBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BridgeBackend

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

Formats the value using the given formatter.

impl PartialEq for BridgeBackend

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