I've uploaded a Rust code repository in the directory /workspace/fd. Consider the following issue description:

<issue_description>
# Add --prune flag

This PR introduces the --prune flag and fixes #535.

The previous PR #546 for this issue has been closed. I'd like to continue the work and discussion on this issue in this PR.

The implementation proposed in this PR is the simplest one I could come up with (which is roughly the initial implementation from PR #546): If a directory matches (regardless of which options caused the match), and the `--prune` flag is set, do not traverse further into the directory.

To start off the discussion, I'd like to address the concerns raised by @sharkdp in the previous PR:
* This is unlikely to break any existing features, as pruning strictly takes place after all the matching logic and does not alter it in any way.
* The performance impact when not using the `--prune` flag should be negligible, as it's just one additional flag to check for each matching entry. I can still perform benchmarks if needed.
* The interaction with other features is pretty straightforward, as pruning only applies to matching entries.

</issue_description>

Can you help me implement the necessary changes to the repository so that the requirements specified in the <issue_description> are met?
I've already taken care of all changes to any of the test files described in the <issue_description>. This means you DON'T have to modify the testing logic or any of the tests in any way!
Also the development Rust environment is already set up for you (i.e., all dependencies already installed), so you don't need to install other packages.
Your task is to make the minimal changes to non-test files in the /workspace/fd directory to ensure the <issue_description> is satisfied.

Follow these phases to resolve the issue:

Phase 1. READING: read the problem and reword it in clearer terms
   1.1 If there are code or config snippets. Express in words any best practices or conventions in them.
   1.2 Highlight message errors, method names, variables, file names, stack traces, and technical details.
   1.3 Explain the problem in clear terms.
   1.4 Enumerate the steps to reproduce the problem.
   1.5 Highlight any best practices to take into account when testing and fixing the issue.

Phase 2. RUNNING: install and run the tests on the repository
   2.1 Follow the readme.
   2.2 Install the environment and anything needed.
   2.3 Iterate and figure out how to run the tests.

Phase 3. EXPLORATION: find the files that are related to the problem and possible solutions
   3.1 Use `grep` to search for relevant methods, classes, keywords and error messages.
   3.2 Identify all files related to the problem statement.
   3.3 Propose the methods and files to fix the issue and explain why.
   3.4 From the possible file locations, select the most likely location to fix the issue.

Phase 4. TEST CREATION: before implementing any fix, create a script to reproduce and verify the issue
   4.1 Look at existing test files in the repository to understand the test format/structure.
   4.2 Create a minimal reproduction script that reproduces the located issue.
   4.3 Run the reproduction script with `cargo run` to confirm you are reproducing the issue.
   4.4 Adjust the reproduction script as necessary.

Phase 5. FIX ANALYSIS: state clearly the problem and how to fix it
   5.1 State clearly what the problem is.
   5.2 State clearly where the problem is located.
   5.3 State clearly how the test reproduces the issue.
   5.4 State clearly the best practices to take into account in the fix.
   5.5 State clearly how to fix the problem.

Phase 6. FIX IMPLEMENTATION: Edit the source code to implement your chosen solution.
   6.1 Make minimal, focused changes to fix the issue.

Phase 7. VERIFICATION: Test your implementation thoroughly.
   7.1 Run your reproduction script to verify the fix works.
   7.2 Add edge cases to your test script to ensure comprehensive coverage.
   7.3 Run existing tests related to the modified code with `cargo test` to ensure you haven't broken anything.

Phase 8. FINAL REVIEW: Carefully re-read the problem description and compare your changes with the base commit a851570b15bbca91f1f4ef230c6d8939f2459ecc.
   8.1 Ensure you've fully addressed all requirements.
   8.2 Run any tests in the repository related to:
      8.2.1 The issue you are fixing
      8.2.2 The files you modified
      8.2.3 The functions you changed
   8.3 If any tests fail, revise your implementation until all tests pass.

Be thorough in your exploration, testing, and reasoning. It's fine if your thinking process is lengthy - quality and completeness are more important than brevity.

IMPORTANT CONSTRAINTS:
- ONLY modify files within the /workspace/fd directory
- DO NOT navigate outside this directory (no `cd ..` or absolute paths to other locations)
- DO NOT create, modify, or delete any files outside the repository
- All your changes must be trackable by `git diff` within the repository
- If you need to create test files, create them inside the repository directory
