MVar

Returned by the apply builder.

Builds an MVar value for F data types that are Concurrent.

Due to Concurrent's capabilities, the yielded values by MVar.take and MVar.put are cancelable.

This builder uses the Partially-Applied Type technique.

For creating an empty MVar:

 MVar[IO].empty[Int] <-> MVar.empty[IO, Int]

For creating an MVar with an initial value:

 MVar[IO].init("hello") <-> MVar.init[IO, String]("hello")

Creates a cancelable MVar that starts as empty.

Like empty but initializes state using another effect constructor

Like of but initializes state using another effect constructor

Creates a cancelable MVar that's initialized to an initial value.

Creates a non-cancelable MVar that starts as empty.

The resulting MVar has non-cancelable operations.

WARN: some Async data types, like IO, can be cancelable, making uncancelable values unsafe. Such values are only useful for optimization purposes, in cases where the use case does not require cancellation or in cases in which an F[_] data type that does not support cancellation is used.

Like uncancelableEmpty but initializes state using another effect constructor

Like uncancelableOf but initializes state using another effect constructor

Creates a non-cancelable MVar that's initialized to an initial value.

The resulting MVar has non-cancelable operations.
