How do I find the files changed in a commit using Rugged?

I am planning to use Rugged for programmatically accessing Git repositories.

I need to find out the files changed in a specific commit.

Commit object provides the following, according to the documentation.

• message
• time
• author
• tree
• parents

I tried the "tree" route, but could not succeed.

I see a similar question asked in SO, in relation to Grit. But, I would like to use Rugged.

In ruby/grit, how do I get a list of files changed in a specific commit?

You can use Rugged::Commit#diff to get the changes between the commit and its first parent or another Rugged::Commit or Rugged::Tree.
