DebuggableSignal
This implicit class provides Signal-specific debug* methods, e.g.:
signal.debugLogInitialEval().debugLog()
See DebuggableObservable and the docs for details.
The implicit conversion to this class is defined in the Signal companion object.
This is not a value class because it needs to extend DebuggableObservable. The performance penalty of one extra instantiation per debugged stream should not be noticeable.

Execute fn when signal is evaluating its currentValueFromParent
. This is typically triggered when evaluating signal's initial value onStart, as well as on subsequent re-starts when the signal is syncing its value to the parent's new current value.

Create a new observable that listens to the original, and set the displayName of the new observable. This is different from setDisplayName
.
Create a new observable that listens to the original, and set the displayName of the new observable. This is different from setDisplayName
.
If you say stream.debugWithName("foo").debugLog()
, the displayName used by the logger will be "foo" verbatim, whereas if you say stream.setDisplayName("foo").debugLog()
, the logger's displayName will be "foo|Debug" – with a suffix – to differentiate it from the "foo" displayName of stream
itself.
