withContext & Structured Concurrency

Compose suspend calls without leaking work.

Composing Async Work

Real features chain several async steps. Structured concurrency keeps those steps organized so none of them leak or run forever.

withContext runs a block on a chosen dispatcher and returns its result. It suspends until done, then resumes where you were.

val u = withContext(Dispatchers.Default) { parse(raw) }
