Struct LayerRegistry 

pub struct LayerRegistry { /* private fields */ }

Registry of LayerFactorys, split into base (always applied) and hints (applied only when a Blueprint declares the matching key in spawner_hints.layers). See the module-level # Factory pattern notes above for why factories rather than pre-built layers.

Implementations

impl LayerRegistry

pub fn new() -> Self

Empty registry (no base layers, no hint layers).

pub fn with_base<F>(self, factory: F) -> Self

where F: Fn(&Engine) -> Arc<dyn SpawnerLayer> + Send + Sync + 'static,

Register a base layer factory that is applied on every Blueprint bind (for layers that must fire for every task — e.g. AuditMiddleware).

pub fn with_hint<F>(self, key: impl Into<String>, factory: F) -> Self

where F: Fn(&Engine) -> Arc<dyn SpawnerLayer> + Send + Sync + 'static,

Register a layer factory addressable by hint key. If Blueprint.spawner_hints.layers lists the same key, it is wrapped at bind time; otherwise it is a no-op.

pub fn base_factories(&self) -> &[LayerFactory]

All registered base-layer factories, in registration order.

pub fn lookup_hint(&self, key: &str) -> Option<&LayerFactory>

Looks up the hint-layer factory registered under key, if any.
