Func wraps a (thread-safe) function as a Value[T].

Merge merges a of cached values.

MergeList merges a list of cached values.

Once calls Value[T].Get() lazily and only once, even in case of an error result.

Static returns constant values.

Transform the result of another cached value.

Atomic wraps a Value[T] as an atomic value that can be replaced.

LastSuccess calls Value[T].Get(), but hides errors by returning the last success if there has been any.

Result is wrapping T and error into a struct for cases where a tuple is more convenient or necessary in Golang.

Replaceable extends the Value[T] interface with the ability to change the underlying Value[T] after construction.

Value is wrapping a value behind a getter for lazy evaluation.
