Import
import { RouteExecutor } from "@typed/router/RouteExecutor";Signatures
export interface RouteExecutor<A, E = never, R = never> {
readonly transition: (transition: RouteTransition) => Effect.Effect<Fx.Fx<A, E, R | Scope.Scope | Router>, E | RouteDecodeError | RouteGuardError, R>;
}Why
Parameter-only updates can reuse a handler; route changes switch scopes deterministically.
Ownership and lifetime
An executor is acquired by makeRouteExecutor in a Scope. That Scope owns its current handler and the
Layer, layout, and catch managers reused across calls to transition.
Property: transition
Decodes and selects the first accepted candidate for one route transition.
Property: transition: Why
Candidate schemas and guards run in their supplied order after path lookup has selected a matcher
shape. Decode failures, guard None, and guard failures fall through; selected identity controls
parameter reuse, and route changes switch the owned handler Scope.
Property: transition: Ownership and lifetime
Calls are serialized by the executor’s semaphore. Preparing a replacement occurs before commit; rejection rolls back new Layer Scopes, while commit closes replaced handler and manager Scopes.
