When to use
Use when you need Layer recovery to inspect more than the typed error,
such as defects or interruption information.
Details
The handler receives the full Cause of the failed layer, including typed
errors, unexpected defects, and interruption information, and returns the
fallback layer to build instead. Finalizers for resources acquired by the
failed layer are still run before the fallback layer is acquired.
Example (Recovering from layer failures by cause)
import { Context, Data, Effect, Layer } from "effect"
class DatabaseError extends Data.TaggedError("DatabaseError")<{
message: string
}> {}
class Database extends Context.Service<Database, {
readonly query: (sql: string) => Effect.Effect<string>
