Enum BackendConfig 

pub enum BackendConfig {
    Redis {
        url: String,
    },
    Kubernetes {
        namespace: String,
    },
}

Configuration for a distributed backend (Redis or Kubernetes CRDs).

Variants

Redis

Redis backend — persistent, horizontally scalable

Fields

url: String

Kubernetes

Kubernetes CRD backend — native K8s integration

Fields

namespace: String

Implementations

impl BackendConfig

pub fn from_env() -> Result<Self, String>

Create backend config from MX_METADATA_BACKEND. Used by both the P2P state manager and the registry manager so they share a single env-var contract.

Valid values: redis, kubernetes | k8s | crd.

Errors if MX_METADATA_BACKEND is unset/invalid, or if the connection env for the selected backend is missing (no silent fallback to localhost:6379 / default namespace, since those mask misconfig in production).

pub fn from_type_str( env_name: &str, backend_type: &str, redis_url: &str, k8s_namespace: &str, ) -> Result<Self, String>

Parse a backend type string into a config. Testable without env vars — callers supply the connection strings directly.

env_name appears in the error message so the caller knows which variable was bad.

pub fn redis_url_from_env() -> Result<String, String>

Return the Redis connection URL from env. Accepts either REDIS_URL directly, or MX_REDIS_HOST + MX_REDIS_PORT (with REDIS_HOST / REDIS_PORT fallbacks for compatibility with charts that predate the MX_ prefix). Errors when neither the URL nor both host-and-port pieces are provided.
