DiscardFuture will start a new goroutine to call Await on the [Future] indefinitely, so the underlying channel is not leaked.

DiscardFutureErr will start a new goroutine to call AwaitErr on the [FutureErr] indefinitely, so the underlying channel is not leaked.

FutureChannel will create a channel that receives the result of the given [Future].

FutureErrChannel will create a channel that receives the [ErrChannelResult] of the given [FutureErr].

Merge will create a goroutine to merge two or more channels into one unbuffered channel.

StaticFuture returns the given value in response to [Future.Await], and [Future.Resolve] has no effect.

StaticFutureErr returns the given value in response to [FutureErr.AwaitErr], and [FutureErr.ResolveErr] has no effect.

SymbolicFuture returns a [Future] that returns a zero value and nil error.

SymbolicFutureErr returns a [FutureErr] that does nothing.

ErrChannelResult is the type returned in a channel produced from [FutureErrChannel].

Future is a value that is resolved asynchronously at a later time.

FutureErr is the same as [Future], but it returns a value and an error.
