maybe
inline suspend fun <Ok> maybeOf(catch: (Exception) -> Maybe<Ok> = ::emptyFailure, scope: RaiseScope<Any?> = DefaultRaiseScope(), block: suspend RaiseScope<Any?>.() -> Ok): Maybe<Ok>
Suspend variant of maybe builder.
Runs block inside a RaiseScope and returns a Maybe. kotlinx.coroutines.CancellationException is correctly propagated for structured concurrency.
The error type is always mapped to Unit; use raise to short-circuit with an absent value.
// Maybe<String> — success
val m: Maybe<String> = maybeOf { "hello".uppercase() }
// Maybe<Int> — absent
val n: Maybe<Int> = maybeOf { raise { Unit } }Content copied to clipboard
