trait Definition[-T] extends AnyRef
Supertrait for typeclasses that enable the be defined
matcher syntax.
A Definition[T]
provides access to the "definition nature" of type S
in such
a way that be defined
matcher syntax can be used with type T
. A T
can be any type for which the concept of being defined makes sense, such as scala.Option
. ScalaTest provides
implicit implementation for scala.Option
. You can enable the be defined
matcher syntax on your own
type U
by defining a Definition[U]
for the type and making it available implicitly.
ScalaTest provides an implicit Definition
instance for scala.Option
,
arbitary object with isDefined()
or isDefined
in the Definition
companion object.
