Module runtime 

AlloraRuntime: aggregate of built runtime components (extensible).

Current contents:

• channels: vector of in-memory channels (single kind)

Future extensions (not yet wired):

• endpoints
• filters / routers
• adapters
• correlation groups

Design goals:

• Single return object from top-level build to avoid signature churn as components grow.
• Provide accessor methods with owned + borrowed variants.
• Keep internal storage concrete now; migrate to trait objects (ChannelRef) when multiple channel kinds arrive.

Backward compatibility note removed: prefer build() which returns AlloraRuntime.

Overview

AlloraRuntime is the single return object from the top-level build() DSL facade. It bundles all instantiated runtime components derived from a configuration spec. Currently it only contains channels (in-memory kind); future releases will extend it with endpoints, filters/routers, adapters, and correlation utilities without changing the public build() signature.

Guarantees

• The collection of channels preserves the order they were defined in the source spec.
• Channel IDs are unique (enforced at build time); missing IDs receive deterministic channel:auto.N identifiers within the same build invocation.
• Lookup (channel_by_id) performs a linear scan; acceptable for small collections. This can be optimized later by introducing an internal index without API changes.

Usage Example

use allora_core::Channel;
use allora_runtime::build;
// Requires a valid allora.yml at the given path.
let rt = build("tests/fixtures/allora.yml").unwrap();
assert!(rt.channel_by_id("inbound.orders").is_some());
for ch in rt.channels() { println!("id={}", ch.id()); }

Future Extensions (Illustrative)

• endpoints() -> &[Endpoint]
• filters() / routers() -> pattern components
• adapters() -> inbound / outbound integration points
• correlations() -> tracking groups for aggregation patterns These will be added as additional fields with accessor methods while keeping AlloraRuntime construction centralized in the DSL facade.
