Creates another Observer such that calling its onNext will call this observer's onNext
with the value processed by the project
function.
Creates another Observer such that calling its onNext will call this observer's onNext
with the value processed by the project
function.
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.

Like contramap, but original observer only fires if project
returns Some(value)

So, similar to contracollect but optimized for APIs like NonEmptyList.fromList
that return an Option.

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
