Type Bounds in Scala are restrictions on type parameter or type variable. By the usage of these type bounds, we can set up limits for the variables. These bounds help to put up our code into real-world examples. We need to impose certain limitations and boundaries to every factor in real life, that is what the Type bounds do in Scala.
There are three types of types bounds supported in Scala:
Here we will discuss view bound.
View Bound is one of the type bound used in Scala. View bound is basically used where existing implicit conversions are used automatically. In some programs, to solve any problem implicit conversions are done automatically. View bound is used to take advantage of these implicit conversions.
[T <% S]
Here, T is a type parameter and S is a type. <% denotes view bound.
Below examples illustrate the concept of view bound in Scala:
