Call hierarchy
RustRover provides a separate tool window for viewing call hierarchies. As you browse through the hierarchy, RustRover automatically navigates you to the corresponding code in the editor.
Analyzing call hierarchies
A call hierarchy shows the callers or callees of a method or struct.
When built, a hierarchy can be immediately viewed and examined in the Hierarchy tool window. The caller and the callee hierarchies are displayed in two separate tabs: click 
to view callers and 
to view callees.
Build a call hierarchy
Open a file in the editor and place the caret at the declaration or usage of the desired method.
Alternatively, select the desired method in the Project tool window.
In the main menu, go to or press Ctrl+Alt+H.
Retain a hierarchy tab
In the Hierarchy tool window, click the Pin Tab button
on the toolbar.
