Struct RouteTable 

pub struct RouteTable { /* private fields */ }

Typed route index.

Two indices: one for Input-kind routes (consulted by the dispatcher) and one for Signal-kind routes (reserved for the signal surface; the dispatcher refuses these with a typed error).

Implementations

impl RouteTable

pub fn from_schema(schema: &CompositionSchema) -> Result<Self, RouteTableError>

Build a typed route table from a composition schema.

Returns RouteTableError::DuplicateInputRoute if the schema declares two input-kind routes for the same (producer_instance, effect_variant) pair. Signal-kind routes are indexed but never trigger duplicate-input collisions (they live on a separate map).

pub fn resolve( &self, instance_id: &MachineInstanceId, effect_variant: &EffectVariantId, ) -> Option<&RoutedInputDescriptor>

Resolve a producer (instance_id, effect_variant) to the typed input descriptor. Returns None if no input-kind route exists for the pair — the caller then returns super::DispatchRefusal::UnresolvedRoute.

pub fn resolve_signal( &self, instance_id: &MachineInstanceId, effect_variant: &EffectVariantId, ) -> Option<&RoutedSignalDescriptor>

Resolve a producer (instance_id, effect_variant) to the typed signal descriptor. Returns None if no signal-kind route exists for the pair.

pub fn len(&self) -> usize

Count of input-kind routes. Primarily for diagnostics.

pub fn is_empty(&self) -> bool

true when no input-kind routes are declared.

pub fn signal_route_count(&self) -> usize

Number of signal-kind routes this table is aware of.
