What is cancelBoundary() (in the last example of https://arrow-kt.io/docs/integrations/kotlinxcoroutines/) ?

[aballano]

it refers to this section in the Quickstart Guide https://arrow-kt.io/docs/fx/async/#cancellation

[simon.vergauwen]

@CLOVIS it's like coroutineContext.ensureActive() and is being deprecated towards it with the new underlying KotlinX runtime.

It's basically to mark a point of cancellation, so if your suspending code gets cancelled it will stop running at the first cancelBoundary() it encounters.
