contextShift: ContextShift[IO]
Provides an implicit ContextShift for the app.
Provides an implicit ContextShift for the app.
The default on top of the JVM is lazily constructed as a fixed thread pool based on number available of available CPUs (see
PoolUtils
).On top of JavaScript, the global execution context is used (i.e.
scala.concurrent.ExecutionContext.Implicits.global
).Users can override this value in order to customize the main thread-pool on top of the JVM, or to customize the run-loop on top of JavaScript.

timer: Timer[IO]
Provides an implicit Timer for the app.
Provides an implicit Timer for the app.
Users can override this value in order to customize the underlying scheduler being used.
The default on top of the JVM uses an internal scheduler built with Java's Executors.newScheduledThreadPool (configured with one or two threads) and that defers the execution of the scheduled ticks (the bind continuations get shifted) to the app's contextShift.
On top of JavaScript the default timer will simply use the standard setTimeout.
