Creates a tagged error class with a _tag discriminator.
When to use
Use when you need domain errors with discriminated-union handling.
Details
Like
Error
, but instances also carry a readonly _tag property,
enabling Effect.catchTag and Effect.catchTags for tag-based recovery.
The _tag is excluded from the constructor argument. Yielding an instance
inside Effect.gen fails the effect with this error.
Example (Recovering by tag)
import { Data, Effect } from "effect"
class NotFound extends Data.TaggedError("NotFound")<{
readonly resource: string
}> {}
class Forbidden extends Data.TaggedError("Forbidden")<{
readonly reason: string
}> {}
const program = Effect.gen(function*() {
return yield* new NotFound({ resource: "/users/42" })
})
const recovered = program.pipe(
Effect.catchTag("NotFound", (e) =>
Effect.succeed(`missing: ${e.resource}`))
)
