ki

A lightweight, structured-concurrency library. This package comes in two variants: Ki exposes the most stripped-down variant; start here. Ki.Implicit extends Ki with an implicit context that's used to propagate soft cancellation signals. Using this variant comes at a cost: You must manually add constraints to propagate the implicit context to where it's needed. To remain warning-free, you must delete the implicit context constraints where they are no longer needed. If you don't need soft-cancellation, there is no benefit to using this variant, and you should stick with Ki. Because you'll only ever need one variant at a time, I recommend using a mixin stanza to rename one module to Ki while hiding the others. This also simplifies the process of upgrading from Ki.Implicit to Ki if necessary.
