final class Local[A] extends LocalDeprecated[A]
A Local
is a ThreadLocal whose scope is flexible. The state
of all Locals may be saved or restored onto the current thread by
the user. This is useful for threading Locals through execution
contexts.
Because it's not meaningful to inherit control from two places, Locals don't have to worry about having to merge two contexts.
Note: the implementation is optimized for situations in which save and restore optimizations are dominant.

Execute a block with a specific local value, restoring the current state upon completion.
The implementation uses the CanBindLocals type class because in case of asynchronous data types that should be waited on, like
Future
orCompletableFuture
, then the locals context also needs to be cleared on the future's completion, for correctness. - def bindClear[R](f: => R)(implicit R: CanBindLocals[R]): R

General usage should be in Local.isolate to avoid leaks.

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomic
types, as alternative tojava.util.concurrent.atomic
monix.catnap exposes pure abstractions built on top of the Cats-Effect type classes:
monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.
monix.reactive exposes the
Observable
pattern:Observable
implementationsmonix.tail exposes Iterant for purely functional pull based streaming:
Batch
andBatchCursor
, the alternatives to Scala'sIterable
andIterator
respectively that we are using within Iterant's encodingYou can control evaluation with type you choose - be it Task, Coeval, cats.effect.IO or your own as long as you provide correct cats-effect or cats typeclass instance.
