How do you implement the routing constraints in Blazor?

A route constraint enforces type matching on a route segment to a component.

In the following example, the route to the Users component only matches if:

• An Id route segment is present on the request URL.
• The Id segment is an integer (int).

@page "/Route"
@page "/Route/{id:int}"

<h3>Routing Id: @Id</h3>

@code {
    [Parameter]
    public int Id { get; set; }
}
