- def contramap[B](project: (B) => A): Observer[B]
Creates another Observer such that calling its onNext will call this observer's onNext with the value processed by the
projectfunction.Creates another Observer such that calling its onNext will call this observer's onNext with the value processed by the
projectfunction.This is useful when you need to pass down an Observer[A] to a child component which should not know anything about the type A, but both child and parent know about type
B, and the parent knows how to translate B into A.- project

- def contramapOpt[B](project: (B) => Option[A]): Observer[B]
Like contramap, but original observer only fires if
projectreturns Some(value)Like contramap, but original observer only fires if
projectreturns Some(value)So, similar to contracollect but optimized for APIs like
NonEmptyList.fromListthat return an Option.- project

- def contramapSome[V](implicit evidence: <:<[Option[V], A]): Observer[V]
Available only on Observers of Option, this is a shortcut for contramap[B](Some(_))

This name should identify the instance (observable or observer) uniquely enough for your purposes. You can read / write it to simplify debugging. Airstream uses this in
debugLog*methods. In the future, we will expand on this. #TODO[Debug] We don't use this to its full potential yet.- Attributes

Set the display name for this instance (observable or observer).
Set the display name for this instance (observable or observer). - This method modifies the instance and returns
this. It does not create a new instance. - New name you set will override the previous name, if any. This might change in the future. For the sake of sanity, don't call this more than once for the same instance. - If display name is set, toString will output it instead of the standard type@hashcode string- Definition Classes
