How does Ruby on Rails know that when calling method: :delete it needs to use the method destroy in the controller?

In the ODOT app, when implementing the delete function for the todo list items we need to add a Delete link: 

<%= link_to "Delete", todo_list_todo_item_path(item), method: :delete, data: {confirm: "Are you sure?"} %>

the specified method: is :delete, but when running the test the failure appears because it couldn't find method destroy

Failures:

  1) Deleting todo items is succesfull
     Failure/Error: click_link "Delete"
     AbstractController::ActionNotFound:
       The action 'destroy' could not be found for TodoItemsController
     # ./spec/features/todo_items/delete_spec.rb:18:in `block (3 levels) in <top (required)>'
     # ./spec/features/todo_items/delete_spec.rb:17:in `block (2 levels) in <top (required)>'

How does Ruby on Rails know that when calling method: :delete needs to execute method destroy in the todo_items_controller?

How does it know that index uses GET? Why does create use POST? It's just designed this way I suppose.
