Rails: How to check if certain user has Ability using CanCan

I know when you want to check the ability, you do 

can :read, Project, id:3

However, what if I wanted to create a page that showed all the users that could read Project #3?

In that page, how would I show all the users that had :read access to the specific project?

Something like 

 <% User.all.each do |u| %>
   <% if u can :read, Project, id:3 %>
     <%= u.name %>
   <% end %>
 <% end %>

Cancan has documentation for this: https://github.com/ryanb/cancan/wiki/Checking-Abilities

Based on your example:

include CanCan::Ability
project = Project.find(3)
User.all.each do |u|
    if u.can? :read, project
      #print the user or something
    end
end
